The quality of those pictures almost surely needs to be changed (reduced, so that you can get them to under 100k) and you'll need a graphics program to do it...try the free program mentioned in this thread.
It's best to just try it and learn - but if it's just a few photos and you're having trouble just email them to me and I'll do it for you, my pleasure.

I realize it's a pain for some - but it's painless once you learn how.
Thanks
