How do I post pictures? any help with that?

Sure...
Start by getting a Photobucket account..or similar
photo sharing site...
Add your photos to it from your computer etc...
Then..as you scroll over your picture in Photobucket..
It shows several "codes"
At the bottom is an IMG code...
Put your cursor over it and left click...
It says "copied"
Then come to post page..In the body of your post...
right click and paste...
If you need to see your fine work...
Click "preview" at the bottom and it will show you
the preview...
Youtubes are different..I'm barely getting
the hang of those...

yep the easy way is to get a http://www.photobucket.com account.

There you can open folders for each subject of photos, make public or private, edit it etc etc

Like omky756 said you just need to copy the [ img] link of the photo [/ img] ( without spaces http://imageshack.us/
