There are two ways to post pictures:

The first is the way it is generally done on forums and indeed was used on PP. The picture to be displayed in the post is located elsewhere on the interweb, on a specialised picture hosting site, e.g. photobucket.

You then enclose the interweb location of the picture and its name in [IMG] tags.

So for example:

[IMG]http://www.somepicturewebsite.com/nobbys_99_raid.jpg[/IMG]

You can type that whole thing into the post or type the picture location into the post, highlight it and bonk the "Img" button at the top of the post window. You're done, the picture will appear in the post as long as it exists...beware typo's.

The second method is to use the attachment option. This appears below the post...

...navigate to a picture on your PC....

...bonk the button and you're done. A second and third picture attachment window will then open, which you can ignore or use to add a further two pictures.

Submit your post in the normal way with it's inane ramblings, using the "Submit" button.

Email or PM CoB if stuck...
