When I create an image using http://bayimg.com, I get a URL such as
http://bayimg.com/NANmnAaCJ, and the image is hosted at
I know that some URL shortening services use mixed case to get an extra 26 characters. However, that doesn't seem to be the case for bayimg.
Why is the URL in mixed case? Can I simply ignore the case and only keep the lowercase version (or is there some kind of hidden feature or future concern I need to worry about)?
