For someone like me who does a lot of block colours in his pics (see the digital comics gallery for my stuff), the 15kb thumbnail limit is too small. There is no way possible to have a 200x200 pixel thumbnail and still keep it under this size. I've tried now with a couple of my past images as well as my latest one and they only way to do it was to set the image quality in photoshop to 0! - which of course by then produced the crappiest quality jpeg ever seen by man. But what of gif I hear you say???!!...well I tried that and ended up going from a 24kb image to 26kb!! - so no luck there. Can we please raise the size limit to at least 30Kb????....
