splash images can be created with jasc paint shop pro 9 in windows, only problem i had was finding a program to gzip it, but there are a few around that do the job nicely.
Err, or maybe it didnt work in jasc, i remember having to change something about how the xpm saves and i dont see it in jasc right now, but i did do it on windows. Let me see if i can figure out how.
Edit, yea it works fine in jasc paint shop pro 9..
:D
