CatDadJynx:
Oh alright, thanks! And yeah, sorry, I meant the adafruit gfx library was what I was using for reference, I'd mistakenly said adafruit ssd1306 (which uses the gfx library). My question was in reference to it though, as in the reference material it says I can use something like gimp to use an xbm file, but I need to use progmem (and I'm not sure how). But I would imagine this may take up a lot of sram, and I need to display three different images for what im doing. I think I see what you mean (somewhat). Thanks!
