Try applying the image you've received from the server as a texture on a plain object. I don't have DB Pro, but I think this is how its done in DarkBASIC Classic (I would think this would still work):
gosub _make_logo
do
rem Your program here
loop
_make_logo:
rem Make a flat surface that is 580x80
make object plain 1,580,80
rem Object 1,wireframe off,transparent black bits
rem do not draw hidden polys
set object 1,1,0,1
rem Texture our object with logo image
texture object 1,1
xrotate object 1,0
position object 1,0.0,0.0,200.0
rem Object is locked to screen until you unlock it
rem with lock object off 1
lock object on 1
return
