Most photographers work hard in protecting their photos from being used by others. This is one of the greatest challenges that photographers are facing when it comes to protecting their work. Despite several techniques like watermarking and copyrights, protecting pictures has become nearly impossible.

Although the Internet has changed a lot of things on how art is shared and distributed, it has also shown a way to steal them. Thousands of photos are uploaded every day on free/paid hosting sites such as Flickr, 500px, Picasa and elsewhere. If the hosting service  provider  says that the photos uploaded are protected, then they are wrong. There are several back entries to gain access to them (Well, viewing the source code is one way).

I have to admit, nothing on the internet can be protected. The best way to protect your art/photos from being downloaded or stolen is to not upload them online. However, it is possible to make image theft harder, but like I said, there is always a back entry.

This article reveals some of the techniques required in order to protect your photos from infringement, ranging from preventing downloads from blogs, finding unauthorized usage of images and modifying your photo’s EXIF data. Let us take a close look at each of these techniques.

Preventing Downloads

Photos uploaded on your photo blog can be prevented in several ways. Here are two basic, yet useful ways – disabling Right-click using Javascript and placing images as a background to Tables.

Disable  Right-click using Javascript:

When you right-click on an image, you have an option to save it. Disabling right-click will prevent visitors from saving your images. To do so, just add the following code in your HTML page -

Place this javascript code after the <head> tag.

<script type="javascript">
<!-- Begin
function disableRightClick(e) {
var msg = "Go hang yourself!";
if (navigator.appName == 'Netscape' && e.which == 3) {
alert(msg);
return false;
}
if (navigator.appName == 'Microsoft Internet Explorer' && event.button==2) {
alert(msg);
return false;
}
else return true;
}

function onRightClick()
  {
  if(document.images)
    {
    for(i=0;i<document.images.length;i++)
      {
      document.images[i].onmousedown = disableRightClick;
      document.images[i].onmouseup = disableRightClick;
      }
    }
  }
// End -->
</script>

Replace <body> tag with this -

<body onLoad="onRightClick()">

Placing Images as a Background to Tables

You can place your photos as a background image to Tables. Doing so, will remove the option “Save image as…” from the right-click menu. Replace the background-image with the URL of your image in the code below -

<table style="background-image:http://cache.techie-buzz.com/images/joel/copter-burnout.PNG');
</table>

Here’s a demonstration of the technique.

Right-click on both the images to see the difference.

Alternatively, you can hide your image behind a transparent image. i.e., by placing a transparent image within the table data <td> cell. This will, however, enable the Save image as…option, but when someone tries to save/download the image, the transparent image will be downloaded instead of the original image.

Here’s a demonstration.

Right-click and save the image below and see what you have downloaded.

Finding Unauthorized Usage

Recently, Google introduced a new functionality to Google Images where users can search photos by just dragging them into the search bar. Impressive enough, however, the feature focuses on finding similar photos, but not exact ones. To find if your photos are being used elsewhere, you can make use of TinEye. Designed by Idèe, TinEye can be used as an alternative to Google Image search. It is a free image search service that allow photographers to upload a picture and then search for the same image across the Internet.

TinEye allows you to either upload an image or enter the URL of the image, in which the attributes of the image are analyzed instantly, and its fingerprint is compared to the fingerprint of every single image in the TinEye search index. It then provides a detailed list of websites that are using the image.

Modifying EXIF Data

Almost all digital cameras save JPEG files with EXIF (Exchangeable Image File) data. EXIF data contains camera settings such as camera model name, lens, shooting mode, exposure and so on.

When you are uploading a photo online, make sure that you edit the EXIF data and add your information (like your name) in the comments field. It is rare to find infringers to go through the EXIF data and modify it. When you come across someone using your photo without your knowledge, you can sue them for it.

Watermarking images is a very popular way of thwarting image thefts. In the past, we have covered several and services which allow you to watermark images for free. However, if you are a webmaster, a recent post on the official Google webmaster blog might change your thoughts on watermarking your blog or website images.

watermarked_images

Peter Linsley the product manager of Google Image search talks about some pros and cons of watermarking images.

Pros of watermarked images

  • Photographers can claim credit/be recognized for their art.
  • Unknown usage of the image is deterred.

Findings relevant to watermarked images (Cons)

  • Users prefer large, high-quality images (high-resolution, in-focus).
  • Users are more likely to click on quality thumbnails in search results. Quality pictures (again, high-res and in-focus) often look better at thumbnail size.
  • Distracting features such as loud watermarks, text over the image, and borders are likely to make the image look cluttered when reduced to thumbnail size.

Google Image Search like the regular Google Search is a huge traffic puller. The findings above or the cons of using watermarked images are definitely worth noting. The reasoning is also quite appropriate as images with watermarks are not that enticing when you actually view it in thumbnail format. However, these findings do not say that you should not watermark your images. Although, it is definitely worth knowing how users react to watermarked images.

Would you as a webmaster stop watermarking your images to get better search engine clicks in image search? It would be interesting to debate on this topic as image theft is rampant, however on the other hand every bit of search engine juice is always welcomed by a webmaster.

Quite sometime back we had introduced you to a online service that would help you watermark your images for free, this included adding a custom copyright to any images that you may own and want to upload on the Internet.

Adding watermark is definitely something you should do when you upload images on the web, since many people may try and gain ownership of the image without your knowledge, using a web service to watermark images could get tedious at times when you have lots of images to be watermarked, since you have to upload each and every image and then download the watermarked copy to your desktop.

Watermarking Lite is a freeware desktop software that will allow you to add watermarks or copyrights to your images by providing a wizard that can watermark bulk images in a single job.

watermarking-lite-screenshot

It supports watermarking JPG, GIF, PNG and TIF formats and also integrates into the right click context menu, so that you can watermark images without having to open them.

Watermarking Lite allows you to choose between 9 different positions for adding the watermark on the image.

Many blogs and websites use images to spice up their posts. Most of them are screen shots or images that have been created using image editing tools. Images can be easily copied by any person and used on their own sites passing of the images as their own. There is not much you can do about it as finding and tracking such image thieves is almost impossible.

In such cases watermarking the images with your own personal copyright is the best solution. Watermarking your images would add your copyright notice to the image and thus prevent the image thieves from passing the images as one of their own.

Watermarking each and every image you create can be a pain though and it is time consuming to add custom copyright messages to each and every image. There is a simple way to overcome this problem and you can do it online at absolutely no cost, yes absolutely FREE.

imarkr-watermarked-image-demo

iMarkr is a website that provides you with a free service to watermark your images. The interface to watermark your image is pretty cool. You can either use text to watermark your images or upload a logo to be used as a water mark.

You can also upload multiple images to be watermarked. To use the multiple image watermarking service you will have to be a registered user.

Watermarking your image can be done in two easy steps.

  • Upload your image.
  • Choose watermarking details.
  • Download the image that is watermarked.

imarkr-watermark-image

While choosing watermarking details you can easily select where you want to have your watermark using the arrow keys provided. After that select the font options and transparency of the watermark. The transparency option can be used to make the watermark more transparent. I have used a transparency of 35% in the image I have created.

You can also use the cropping tool to crop the images. If you do not want to crop the image simply click on the Remove Cropper button to watermark the entire image.

Once you have selected all the options click to proceed to the next step and you can download the watermarked image. In addition to the watermarked images you will also get direct links to the image as well as links which you can post in forums or MySpace.

Main Features Of iMarkr

  • Adding customizable visible watermarks on your pictures or digital photos.
  • Crop Images
  • Custom transparency
  • Watermarking a group of pictures (batch watermarking)
  • Watermark image(s) with your logo.
  • Add custom font and color to your text
  • Select the position of your text or logo (i.e. top left, right, etc)
  • Auto create codes to use on forums, MySpace and direct linking
  • Host your watermarked images.
  • View your images in user gallery, slide show The site is very easy to use.

My 2 Cents

iMarkr is a real cool tool and it should save a lot of time in watermarking images you created. This would definitely decrease image thefts as it would become harder to remove the watermarks from the image. I did not see any loss in quality of images that were watermarked.

I definitely would recommend this to anyone who puts in some effort to create images. Also this service can be used to watermark your images before uploading them to public websites like Flickr or Picasa. Registering for an account is a great option as you will be able to watermark multiple images thus saving you lots of time.

What do you think about this tool? Do let me know through your comments.
