-advice about your problem:
1st if you are under Linux , stop reading , this advice can't help you.
If you are under Windows , you can continue.
You should use
this 3rd party OpenGL render for UT.
Extract the file you will extract fomr the .zip you can download directly by
clicking there " OpenGLDrv " to the folder named System that can be found in ...\UnrealTournament\System\
Overwrite the file already there that has the exact same name.
Now launch UT with the "safe" mode shortcut of UT that is located in your Start -> Programs -> Unreal Tournament menu.
select the option "Change your 3D video device"
if OpenGL is not in the list, tick the case "Show all devices"
Select OpenGL Support and click Next.
After all it will launch UT in OpenGL , with the very good 3rd party renderer that you have installed previously.
This should really get rid of your problem.
If not , more help involving the content of the UnrealTournament.ini file should follow, but 1st : install the 3rd party OpenGL and select OpenGL as a render for UT by following the advice up there.
Notice : you should download the utility named Irfanview that Glider of Chaos mentioned , it is a really great utility that i use since some years.
Support lot of picture formats, quick and easy browsing of a directory full of picture , mass pictures conversion from a format to another.
And it is free.
