e -ink

Hey I'm using an e - ink display with c array files, does anyone know how to either write text into an e ink screen or shift the image when printed? the issue is I have 7 images I want to display and with the full screen size of 172x72 pixels i cannot store all of these images on the flash memory of the arduino as there is simply not enough space. Several of the images are just single letters but in reducing the size I allow for print overlay to occur. Please help
