Debi -
this is how to post a photo in general (within a post). Posting a profile photo is basically the same idea.
Go to
http://photobucket.com and sign up - it's free.
Once you move your photos to photobucket, it's easy to copy the image. Look for a series of boxes under each photo that say "email & IM", "direct link", "HTML code" and "IMG code" Position your mouse on IMG code and left click. A yellow box that says "copied" will appear.
In the text of your post, just right click with your mouse and choose "paste".
You will see a set of brackets with the letters IMG in them and the address of your photobucket photo inserted between the brackets.
If you have numerous photos to post, just copy and paste each IMG code.
If you want to check and make sure your image(s) copied correctly, just "preview" your message before you hit "post" and you should see your photo in the preview box.
Good luck,
Jan
