All of my screenshots are in .BMP format. I see a lot of folks posting screenies from Imgur.... but when I upload a /BMP to Imgur, it only shows up as a blank, white page. I have te convert it to .jpg to get it to show properly.

Is that what the rest of you are doing?

I use photobucket

Stop taking BMP images?

I use Flickr, but I would say you should check the upload requirements of Imgur, or their help page. Whatever they recommend will probably be better advice than what you get here.
