Hey all, sometimes we see users who posts BMP files, which is sometimes an annoyance to some AGS users. Well, I found the tool that helps those who uploads BMP to convert it into another format.
http://www.moijk.net/blinktools/resize.php
The site is in norwegian, but is probably easy to understand.
Find the BMP image by first clicking on "Bla igjennom", after you've found it, choose the resolution (one of the top three), then press "Send fil". Now the BMP will be uploaded, and converted right away.
Hope this helps.
