Yupp, would suggest pure pixmap here as well.
A slideshow does not need realtime normally.
The only problem is that the alpha, scale etc commands only apply to images.
But another thing that puzzles me a little: Do you have 3000x3000 screen? otherwise the 100 thumbs won't be onscreen which means that the images do not need to exist as well.
PS: not even asyncron file handling will solve the problem as the largest part of the loading of an image is the upload and especially the mipmap generation. So by disabling mipmap and filtering it should already speed up considerably.
PS: 1024x768 actually means 1024x1024 and if you didn't make sure you don't load with mipmap, this is actually around 6MB not 4MB (it will never be 3MB no mather what you do)
