Suggestion: Search for all the keywords
I'm populating and trying to educate my users to fill all the lines when they upload an image, specially the one dedicated to words, because will be quite easier to search anything in the future, when the number of images, categories and others explode.
Searching for some keyword is ok, but could be great to make a search for all the keywords (or some) present on a image. Could be considered for a future release? vBGallery rocks and is getting better and better on each release.
