'waste of internet bandwidth', if i use a compressed image format will it make a difference to the filesize even though its zipped (i know f-all about compression)
Not if you leave them as 24 bit color BMP's, but you can have 256 color PNG's ( which in many cases may be unrecognizable from their 24 bit color versions ) and those will be considerably smaller, even when packed.
oh and the soundformat is mp3, never heard of ogg, what is it, is it better and can i convert?
Ogg is better, if only because you have to pay a hefty license fee to use MP3 in a game. The quality is very similar and the filesize is *possibly* a little lower with Ogg. No bigger though. Yes, you can easily convert with DBPowerAmp. It even has shell integration so you can just right click on an MP3 and there's a "Convert to Ogg" option.
I'll download to take a look a bit later. Probably leave it downloading when I go out this afternoon and let you know what I thought tonight.
