If you try imageShack
http://imageshack.us/ You can host your photo and size size it in one click, a good size to use is 640x480 after you upload the photo go to my images and copy and paste the link for forums. Make sure the photo is under 1024 k or 1 meg.
Note it will look like this in your post:

If your photo is larger than 1 meg; on your computer you should have a photo program like Paint? go to Programs/Accessories/Paint
open the photo
go to Image/Attributes and change the pixels to 640 x 480
save as a different name
now it will also be small enough to post as an attachment.
BUT...If you use ImageShack or a hosting site it saves on bandwidth on ATVFLORIDA and Mr. Bones is a Happy Camper
