The thing is that unlike some forums, Pprune does not host pictures directly.
This means that you have to have another service that will do it for you. Photobucket is a popular one. It's a free download.
When you have set this up, you simply pick a photo that you've put into such a program, and then
copy the IMG Code...which in Photobucket's case is the fourth line under the thumbnail picture, and then
paste it into your Pprune posting.
So, I would put in this link and the picture will appear, except that for now, I have corrupted the [IMG] bit with some *** so it doesn't work, and you can see what it looks like.

Now, when I remove the *** it will automatically show the picture...as below. You will see that it causes the scroll bars to appear because in this case the picture is a tad too big. Not good, but more on this below.
Mind you, I have intentionally 
picked a picture which is too big...this ticks people orf, cos from then on all the folks looking at that entire page will have to scroll sideways.
The Bucket, as I call it, can re-size pictures, but there is a nice little freebee called FastStone photo resizer. There has been a thread here or in Jet Blast - in the last few days - on getting the size right for Pprune...but as a rough guide, a Med quality 125K comes out about right.
Getting tricky? Don't panic. You can simply invite folk to look at your picture without showing it. This kills two birds with one stone. A/ It is just that, an invitation to look, and B/ The size problem goes away. So, you'd just DEL the [IMG] boxes off the ends...for some reason, the picture is always a nice size. ( I think...I haven't tried any vast ones.)
