You can put as many pics as you want in a post, just enclose the URL of the pic between "[PIX]" and "[/PIX]" and substitute PIC for PIX.

Example:

These are three pictures from my Website:

[PIX]http:\\yourwebsite.com\picture1.jpg[/PIX]
[PIX]http:\\yourwebsite.com\picture2.jpg[/PIX]
[PIX]http:\\yourwebsite.com\picture3.jpg[/PIX]

And remember to substitute PIC for PIX. I have to do it this way, otherwise The ChipBoard formatter would attempt to load pictures, instead of showing you the text of how to do it.
