New feature to posting Images!

[JRgraham]

I have finished adding support for image viewing.

Viewing images on topics will now display in a Pop Up Slide Show, rather than one view, clicking back, and viewing the next.

This should be hassle free, but like anything else added to the system code, there could always be some conflict or issue.
Please report any strange behavior you may notice, even though I really do not anticipate much of any problems.

Thanks, and enjoy!
