no way to store images in PROGMEM, call one in SRAM, and display it in a bitmap

I don't understand what you mean by that.

• You could have many bitmap in Flash/PROGMEM and your code could decide which one to display
• You could have bitmap(s) in SRAM and your code could mess around with the pixels if you want to and display
• you could select a bitmap in Flash/PROGMEM, load it up in SRAM, mess around with the pixels if you want to and display

everything is possible
