How do you make your own picture for the Radio Room
what are the dimensions?
I found this information from a previous topic on emblems
and it worked :
If you want to make your own emblems, they must be saved as 256x256, 24-bit color, uncompressed Targa (.tga) files. Use an alpha-channel mask to make the background of your emblem transparent if you wish for the u-boat's paint to show through.
