Hey guys, beware!
I hope you all know about Content Plagiarism (copying/usage of your content without your permission). I have a blog, where I have been using most of my captures for about 1.5 years now. Just a few days back, I found out that some of my images are being used in various websites, without my knowledge, let alone, seeking my permission. While, we have been sharing our captures here on this thread, and at a lot of other places, I believe we never care to check out our images for wrongful application.
I do hope that each one of you would check out for your images being used elsewhere on the internet without your permission. While we have a lot of tools to check for text contents, including Google Search, Copyscape, etc, to name a few, good plagiarism checkers for images are hard to find, in terms usability. If you're planning to search for your content's illegal usage, you can use images.google.com, Reverse Image Search by Image Raider - Track Photo Usage. While Google images has a drag-and-drop UI where you can drag and drop the images and add some text to help it find better, imageraider works with image url's. Hoping that you guys will get some help with these tools.
