I've been doing that on forums for years. The old V-Bulletin forums use 'manage attachments' at the bottom, below the text box you opened, or an 'insert image' icon which give the same options. The best part of that is that the photos will never be deleted if the internet account, with photobucket, or whoever is deleted.I've finally figured out how to post photos on here instead of using Photobucket.
It was one of those facepalm moments which I tend to have on a daily basis.
Click on the 'Upload a file' and 'choose a file' window pops up. Clink on that and a couple of options pop up including 'My Documents' clink on that and choose a photo. Wait for it to load and two options appear at the bottom of your post. Either a thumbnail or full size. Choose and post.
Simply when you know how....walks off sheepishly.
If anyone has already mentioned this up thread I apologise.
