Well, presently, I'm using .PNG files. One thing I have not yet tried, is to resize the images because I'm wondering if this is an issue with allocating and storing images that must have a size to the power of 2. I.e. 8x8, 16x16 etc. I'll test this hypothesis and come back with what I find.
[EDIT] After resizing the first .PNG image (Splash) to 1024x1024, it unfortunately still appears not to display. I need to determine if this is a display problem, or that the images are actually missing.
[EDIT] I have tested this with the latest Android player as well, and this also exhibits the same problem. Has the "Media" folder structure changed or something that I've overlooked?
[EDIT] After doing more investigating, I think the problem doesn't stem from image loading after all. I think the problem maybe to do with FileRead because I'm using an assets file to preload images, and this is what is now failing to load.
