It looks better now. How do you know who is stealing your work? Is it possible to do duplicate image search or something?
No one stole mine (atleast till now, I haven't come across that

), but instances occurs every now and then, on a blogging forum I'm a member of, so, I just keep it simple - don't upload unwatermarked images, and even when you're uploading watermarked ones, keep it low resolution, if it can work, like here on Flickr, or even in my blog posts, I keep it at 1600x1200 only, can save the bandwidth along with the intended purpose. Other than that, at my download gallery, I have 5mp images with minimal watermark to spoil the view.

As far as image search is concerned, just do an image search with google, and you'll get all the similar images from all the sources.
