The easiest and best way to do it is from a photobucket, imageshack or similar image hosting service. You basically upload the pic then insert a link into your post. Surround the link with following minus the *: [*i*m*g]link here [/*i*m*g]
Photobucket used to be great...then the picture filed began to start corrupting and messing with the URLS, etc. I switched over to Picasa and have been happy ever since... I would highly reccomend it, :bigok:
