Welcome to The Forum, to help a bit once you have managed to up load your photo, to say Post images. Then go back to the PC forum page and the reply, on the top bar above the smileys, there are two, a square one and round one both with little chain links. Click on the square one. This opens up another two windows, the small one when you select will show 400. Click that. Then delete the next one down //http. Then click that and "paste" your photo link. Then On the next box press insert. Click on preview, and after several attempts, you might get there.
Also go to the Photography index on the forum.
Good luck
Hutch.
