uberzev........... a 128x128 image, enlarged to 192x192, will not look as good as a 256x256 image, reduced to 192x192. Now, you may say, "why not upload a 192x192?"..... one  reason may be that the image is used with another program, that uses 256x256, and rather than create a new version, the author uploads the larger image. ......... I hope that explaination isn't even more confusing, but I tried..
