But while the library might be large, the computation would be eased - and you could easily compress the library (graphics often will compress considerably, especially if the files are minimal (say 4 bit colour - or even 2 bit b/w) colours and have lots of space the same colour) - a zip file to be unpacked (even self extracting) on install. You could even do the whole install that way... :-) You then just load the graphics on startup.

One of the Win 3rd party utils - forget which one now - allowed you to build self extracting libraries, - if that means that you need 7-zip to extract it on WINE, don't worry, that is one of the things that WINETricks will install!
