I didn't think photo bucket existed any more.
Why not use the "Attachments and Other Options" Then go to Attach: Then go to browse - which takes you to you own computer a select your pic - when selected the name of you pic appears just to the right of Browse meaning the pic has been selected = then hit Post at the bottom
See the pic I attached below and follow the coloured arrows
- click on the pic to get it full size.
Easy Peasy
