easiest way is to just do a google search for "image resize" and use a free program. lets you upload your pic and resize it, then re-save it on your desktop or something. upload the resized pic to spudfiles.

heres the one i like
http://www.resize2mail.com/

click upload... select picture... click the bubble next to 75% then go. right click pic from the internet and save it. upload that to spudfiles.

I like to use sights like photobucket because its fast and I don't like the SF uploader, but its personal preference.

Good free photo editor.

The Gimp is a free full featured photo editor. It can do most things you would want to do including crop, resize, adjust color, brightness, add text, etc. I use it to scale my photos to new sizes and crop them to remove unimportant distractions from the photo.

The Gimp is open source.. Feel free to copy it under the GNU license.
