very satisfied with Photodune, but I have a comment regarding image search. Is it possible you implement the possibility to search the image by file name, code?
The problem is, that it is very hard to find pictures again, once I saved them to my computer. Example. I am making a website design, and I look for a bunch of mockup pictures to use with it. Client approves it, but it is a problem to find theese pictures again, since naming is not properly set. Author gives some random, not searcheable, name.
You probably know that, but at various other PhotoStock sites, I can simply paste the number code (filename) of the picture in the search field and image gets found.
It would be great to have this feature here. I use it a lot, and I bet lots of others do too.
