Ok, here's a quick and dirty way to create your own emblem using Photoshop.
I do not know how this works in GIMP as I've never used it
Go here and download the DDS plugin

*Note: As far as I'm aware this plugin does NOT work with 64 bit versions of Photoshop
Put the plugin in your main Photoshop folder:
C:\Program Files\Adobe\Photoshop\Plug-Ins\File Formats
Ok.
Download Etheberges "A Fistfull of Emblems"
http://174.123.69.202/~subsimc/radio...d.php?t=164789
In Photoshop open the "custom" dds file in the "Fistfull of Emblems" folder
Data/Textures/TNormal/Tex/custom.dds
This window should open in Photoshop
Select "Convert Images to 32 bit"
You should see this image
Select "All" and delete the image of the playing cards
Go to channels and delete the playing cards ALPHA channel
We don't need this because you are going to create a new ALPHA
Go back to LAYERS
Import the image you want into Photoshop. Resize it to fit if needed.
Make sure the image is on a single LAYER. FLATTEN the image in LAYERSs if not.
Now make a selection OUTSIDE of the image as shown below.
In my image I clicked on the white background.
Now select "INVERSE"
Go to CHANNELS and CREATE A NEW CHANNEL. This now appears as a new ALPHA
Now simply press DELETE
Your image now has an ALPHA (Remember. White = image. Black = transparent)
Click the top ALPHA CHANNEL marked RGB
Now SAVE AS the dds file
This window should pop up when you SAVE AS dds file.
Select DXT5 as shown
You're done! Simples.
