After many a moon of browsing and looking over other folks electronic shoulders, I guess it's high time for me to join the fun.
Besides, it's another excuse for not getting any real work done...
I tried to upload a simple 11k JPEG of myself, to use as my "default" picture, and got this nice little error message:
The dimensions of your image (89x129) exceed maximum size. Your picture can only be 100x100 pixels large. Use a image/photo editing program to reduce the image to thumbnail-size.
Ah, the joys of learning new tools.
