I think this is fantastic, I definitely like the auto-thumb idea. I prefer to see the whole pic in a thumbnail as I get a better idea of what the image is about. I’m not a great fan of a section as a thumb, personal choice only though, I know a lot of people prefer the section type.
The only problem I could see with the auto-thumb method is images containing any form of nudity. The thumbs would show the whole picture, and we just know there are some politically correct people out there that could manage to get offended by an 80x80 image… just a thought.
Top marks to you Leonard.
