Mac Avatars HELP!

Hi, I downloaded the mac version of kudos, and I want to know how to ad avatars? somwhere cliff had said that the mac version takes png, not dds- so someone else converted all of the new avatars into png format, but i found that none of those work. they always come up as a white box. does anyone know what format the mac version does take? i’d really like to update my avatars!

also having trouble with the avatars. some work and some don’t, and some work fine until you add another update

the punk worked fine, then i added another avatar and now it’s just a white box and the black guy works fine. i want the punk back. i hope this gets fixed
