welcome Steve G Shop,I'm Yuth.
For me,I send picture to this website by openning my album at
www.photobucket.com first.Then,copy photo at "img"name.Then paste it to cokethai newtopic or reply board.
If you have photo on the other website,you can copy by click with right finger on computer mouse and choose "Properties" item.Then copy address and paste it ot cokethai newtopic or reply board...not finish yet.Then choose all of the picture name and click "img" for change your picture in img-name.That's finish.
I hope to see your photo soon.
