I'm going to put together a wide layout skin as an option, but it will apply to the forum only. What some view as wasted space, others view as a layout more appropriate for actual reading.

Another "light" skin will be available soon. I just didn't have time to get it ready for this update.

Regarding images...I'm working on something. I know it's annoying when the images get clipped, but honestly, all these giant images have no business being embedded directly in forum posts anyway. It makes pages take much longer to load for those on slower connections, and I'm regularly annoyed by the "jumps" that occur when I use the first unread post link on a topic, drop down to that post, and the contents continue to shift as images load at the top of the page. This doesn't happen all the time (God bless FIOS), but when the server is busy, it's annoying as hell.

All I can suggest for now is using links to images instead of embedding them. It's entirely likely I'll disable the ability to dump full-size images in posts.

yeh, i've got to say that some of the images are getting ridiculously large now and many not even compressed. Maybe restrict images to imageshack thumbnails or something similar, maybe even change the "insert/edit image" icon in the reply tab to turn any images into thumbnail links?
