I already know that if you make a powerpoint on mac, images won't show on a pc. Well is it the same the other way around. Say I were to work on a powerpoint on PC, would it work on a Mac?
i dont think it does.
cause i did that once for a school project, and none of my pictures worked.
i used a pc at home, and went to school and plugged it into a mac, and then they didnt work.
That works with my computer... If I use Keynote and turn it into a powerpoint, it's multi-platform. Being as the images, the music, everything works on either a Mac or PC.
I don't know why it doesn't work for you. Another solution would be to bring the images on the drive and then put them in place before the presentation.
