This takes some figuring out! Firstly, this site won't upload photos directly, so they have to first be uploaded to a picture hosting site like Photobucket or the like. Once there, copy the "direct link". On your post here, click the "insert image" button (second row, right under the "BOLD" button) and will show up with your cursor in the middle of the two "[img]" thingeys.... paste your link code in the middle. When you think you have it right, click "preview" below this text box to make sure it looks like you want it to!
Hope this helps!
Can't wait to see your photos!!
