The size limit of 100K is a problem because considerable compression is needed to get down to that size. Some of my originals average 30 meg.
The results of compression to 100K are pixellation, artifacts, picture noise, and compression of the histogram affecting shadow colours and detail and or midtones. Even highlights that have detail in the original can be washed out in the compression process. Sharpness can also deteriorate and banding can appear through loss of tones in the small jpeg image.
If the server can handle 16 bit jpegs (some editors will produce them) or other 16 bit formats it would help. At the same time, critiquing an image becomes less valuable if the uploaded image due to compression is considerably different from the original.
