Simple Way to Draw a Progmem Image Onto TFT Screen?


I've finally got my 1.8'' SPI TFT (ST7735-driven) up and running, and I would like it to display a simple image from prog memory. So I am looking for a way to have an image that is defined by

const unsigned short myImage [] PROGMEM = {}

simply put onto the screen once, in a designated pixel location.

I haven't really got the hang of TFT displays yet, and I have tried to modify the library examples to my needs, but it doesn't quite do what I want yet.

Is there a simple "quick and easy" way of doing this with just a few commands?
