To make your custom clan logo, you need to edit clanlogo.iwi (in eod_really.iwd).
You will need to convert this to DDS, so you will need converters to do this. These can be obtained here:
To convert an IWI file, place iwi2dds.exe on your Windows desktop and just drag and drop the IWI file onto it, and the converted DDS will
pop out the other end (where ever the IWI file is located)
You will also need a DDS plugin for your image editor (Photoshop, Paintshop Pro, or GIMP).
A Photoshop one can be obtained here:
Once you have your logo, convert the DDS file back to IWI with the converter obtained in the link above.
To convert a DDS to IWI file, place dds2iwi.exe on your Windows desktop and just drag and drop the DDS file onto it, and the converted IWI file will
pop out the other end (where ever the DDS file is located)
You now need to place it in eod_really.iwd\images folder.
