my suggesting is that i used it once and i used a random .nds file b/c most card nowadays autoDLDI which makes them useless so it rly doesnt matter

img viewer uses a special format called .ipk u can convert .jpg and other files into that format

theres also another imageviwer program called comicbookDS(mainly used for manga and such) but its a better one than img viewer in my opinion

 

Thanks geniusgeek, I got image viewer to work now!

I'll look into ComicBook DS as well... does it do eBooks too (text, not comic), or only images?
