The only way I can see to do it is actually just preload the images (say 1 to 20) and then keep using setobjectimage... Is this the best way?
I don't see any way to us an image atlas...

I guess you could render an animated sprite to an image, and then use that image as the texture on your plane?

Loading all the images and using SetObjectImage would be the best way, although if you can fit them all on a texture atlas and load the images with LoadSubImage then that would be even faster. Just be careful about how much memory loading all the images would take, for example 10 images 2048x2048 in size would use 160MB of memory (2048*2048*4(bytesPerPixel)*10(numImages)).

Hey thanks...

just to follow up say I use 20 images 256 x 256

any way to check the amount of memory I am using and -- generally don't go over how much memory to use?

I did already load 1 of these images and made 50 sprites and put them at -100,-100 I am guessing that does not take as much memory...

A 256x256 image would take 256*256*4 bytes in memory which is 256KB, so 20 of them would use just over 5MB, which is no problem. Using a single image on 50 sprites is also no problem as they all share the same image and sprites themselves use much less memory compared to images.
