I don't know how you guys do it with paint.. it's an AWFULL program.
And you have to do it by hand ...and it jogs the pixles to make it look wierd.
Try a programme like PhotoImpact.. or anything that came with your computer (i.e. any other program that edits images) ..go there and just type in resize into Help (if you don't know how to do it) ..then follow instructions. If you type in 100px in the width box (when it asks you to which size you would like to resize it to..) it will resize the height accordingly...
If that's to confusing and you can't do it so it looks fine on paint... send the full sized photo by PM. I'll do it.. takes seconds
