Hi Martin
I uploaded a few pics to the forum and I found that the easiest way is:
Open an account in Photobucket, go here and just follow the procedure...
http://photobucket.com/register.php?ref=headerregister
After you upload the pics to Photobucket, you will see under each pic
URL Link
HTML Tag
IMG Code - that's the one you need
Left click on the IMG Code... not on the "IMG Code" but on what is to the right of the "IMG Code", it should be "http://......photobucket" (when you put your courser on the text, the courser will change to "I" shape).
When you left click, you will see that the text background turns Blue and the word "Copied" on a yellow background will appear momentary.
On your post, right click on the place that you want the pic and on the drop-down menu choose and click on the "Past".
If you want to upload another pic to the post, go again to Photobucket and repeat the procedure
Preview your post and you should see the pictures
Hope it helps
