Yes, I'm the admin at the BX wiki. (I've been less active in the last year due to a change in my commuting patterns limiting my screen time). Actually the point of making it a "wik"i is that anyone confident enough to edit pages can be a "Writer" and contribute. Minimal computing skills needed - if you can edit MS Word you already are overqualified the wiki
Just join as a member (if you are not already) and then make a request to be a Writer. (I think there is a button for that. I will make a fan replacement page (as a sub-page) of the existing fan page and your photos and narratives can go on that.
The only thing worth noting about photos (and that goes for any photo to be published on the web on ANY site) is to reduce the resolution so the file is not massive. On that toothbar page the photos are about 400 x 300 pixels and take up only about 30K bytes each. (I cringe when I see a 2 megabyte image embedded in a web page - it really slows the display of a page.)
Most photo software these days (like Picasa, Photoshop) etc has an option to export pictures and choose a suitable resolution for publishing or emailing. If yours doesn't, there's an excellent free image viewing/manipulating utility called Irfanview that will do it.
You can PM me with additional tech questions about the wiki. No need for me to bore everyone here with more geeky details
