Here's a couple of pictures to try and help.
OPen up your photobucket account - you should see your 5 pictures as small pictures all on one screen.
If you move your arrow over a picture, a little menu will drop down with 4 lines of text. It will look like this:
As my added arrows tell you - you right click the bottom line of code, and "copy" it.
You then paste that line of code into your post here, and when you submit the post, the picture will be displayed.
Another way to do it from photobucket, is to click the little picturte, and you will then get a larger version of it. The same 4 lines of code are next to the picture. Again - highlight the bottom one (called IMG Code) and copy it, then paste it into your post.
Good luck!
