Reverse Image Search Issues

[PhotoGramly]

Since it's not really plausible to prevent image theft, it would be nice to at least check periodically to see if/where it happens to my images. I'm well aware of reverse image search tools like Google or TinEye (among others) but I've found that when I check there, they can't even find them on my own website, much less other websites where I know for a fact that it's being displayed, such as the listings featuring my real estate work. Has anyone else had this problem? Did you ever come up with any solutions?
