Ygrec23, it may help to upload your pictures to a free site like www.photobucket.com

You can then "edit" the pic and resize it i.e. extra small, small, medium etc. Medium is usually a good size for posting here. I posted the following on the bipolar forum and I hope it helps:

To get pics on posts, profile pages I use this site: http://photobucket.com/ You can upload your own pics or choose from their pics. You can save pics from their options in your album. At the top of the pic you will see a tab that reads "share" click on that tab. Then click the "get link code" tab. Choose IMG for bulletin boards & forums (4th choice). Copy the link and when you paste it in a post or profile page it will automatically show the pic. Let me know if you have any problems.
