Is that the only search option; section and keyword? I tried a few searches and got what I expected to see. But what if I want to see starter motor pictures posted by Joe Blow. What I don’t see is the ability to search by the name of the person who submitted the pictures, I think that would be useful. A date range would also be nice.
Another point is that as far as I can tell the search is pretty much dependent on the description the original poster created when they originally posted the picture. It’s always been that way and I don’t know how to get around it unless someone is tasked with looking at every picture creating tags based on what they see. I think this points up the need to somehow remind people to take care with their descriptions of pictures.
