Getting the pics to Chris is probably the best way in the long term, as the photos will be archived along with the site. If you host the photos yourself, and your later switch servers, the links in the forum will break. Not really a problem if you take care of your posts, and it does make it easier to post since you don't need to wait for Chris to find time.
I've started using
www.photobucket.com to host pics. They provide a free (donations appreciated) service and the results and interface are nice.
To link to a photo, you put the url between {img]...[/img] tags (but replace the first curly bracket with a square one)
Here is a pic:

Hope you figure it out, we all like pics!
