If you put your cursor over the top of your picture in photobucket, you'll be given different size options.

Shirley, you can always re-size any photo by adding width & height attributes to the code for the photo that you are posting. Preview message & re-size until you like it. I can go into more detail if you are interested.

I don't know if the OP in another thread ever saw or wanted to use the info on the link below but I tried!
