just needed help to put a few pics on here of my pigeons
The easiest way is to create an album. Click on "User CP" up in the top left corner of the page. That will take you to YOUR personal page. You'll see a link to create an album. Put your pictures in the album and once you've done that, you can either provide the "Picture URL" in a post OR you can copy and paste the "BB Code" into your post and the picture will appear.
Doing it this way, there's no resizing of pictures.
