The header images? They should be 750 x 128. About 550 (from the left) is where the linklist will start so the area past there should be fairly blank and dark. The left and right edges of the banner should fade into #000040 so it blends smoothly.
I roll up in businesses and talk owners into letting me present cool heath coverage options to their employees. Aflac insurance rocks because instead of paying the healthcare system they pay the policyholder. Also, they stack with other health plans.
After reading this thread I suddenly had the urge to doodle a sexy Christmas-themed Neko on my laptop. Laptops aren't Photoshop-friendly due to RAM requirements so I did this in Microsoft Paint, thus the rough art quality of the drawing in the above link.
I thought it'd be hypothetically funny to have various ships' Morale Officers being forced into lingerie for a photo op, then have their photographs distributed fleet-wide via a complimentary Christmas pinup calendar to "raise the morale of the fleet" during the holiday season. Mwahaha. Yes, I realize there is no Christmas in SARP, nor are their Morale Officers. But it was funny to imagine at the time.
I only wish I had drawn her lying down instead of sitting up so she could fit in a header bar. >.>
