I find this as an accidental omission that the thumbnail view doesn't tell you what the image is. I see all kinds of other info that is completely irrelevant to the average user like image size, views, poster, date... but it doesn't say what the image is... I have tons of images that look the same but are completely different (game fansite). Randomly clicking on thumbnails until my members get the right image is a complete waste of bandwidth when they could just scan through the thumbnails and click the one that has the right name on it.
I will be looking through the gallery to fix this and post an edit mod for others to use later.
Just thought it should be part of the gallery from the start. I like the gallery GJ (lite should have subcategories though).
