This is a group where people create and upload banners for all to see and use on ModDB. Pretty much as simple as that.
Made basing on the background that can be found here:
indiedb.com/mediakit
Media.indiedb.com
Also that original IndieDB pack contains the font used in official IndieDB promotional artwork, called TinyPixy.
You can also colour them to diversify the artwork a bit (example of not IndieDB, but ModDB coloured banners here: Moddb.com).
Goodie goodie. Thanks!
I made a section in the forum for posting resources like this, so as to help keep the image section a bit more clutter free.
