I have found a free online picture resizer for those having trouble uploading photos:
http://www.picresize.com/
To place a picture in the body of your message, scroll to the bottom of the "post new thread" or "reply" box and click "manage attachments". That will open a window to upload your photo:
Remember these important dimensions:
For an Avatar ( The picture that apprars on each posting) cannot exceed 300 pixels (largest Dimension)
For a Member Profile picture, do not exceed 400 pixels (largest dimension)
For posting within a message, do not exceed 620 pixels (largest dimension)
Warmest Regards
Joe
