Where are you trying to upload it to? I wanted to look at the rules and instructions and see if they threw any light on the subject. I don't see any albums listed at your profile but maybe an album doesn't officially exist until you have one or more pictures in it.

I use a dialup connection so pictures take a while to load and I have to be selective about which ones I pick to look at. I can hardly imagine something that would tempt me to wait for a 3MB monster to load unless I was about to go cook dinner and expected the picture to be there waiting for me when I got back.

Sometimes when my connection is slower than usual or a site is unusually busy (with users or housekeeping), it's hard to get any large file to load completely, whether it's a video clip, a big still picture, a .PDF, or an update for an application.

I'm with pachy on this one -- by all means, reduce the file size of your picture.
