user21098: I just recently resolved my problem on getting images to load on to my TFT display via the SD card. Thanks to UTFT_SdRaw!!! it's by far the easiest to use. For a novice like me, its been a real feat. Now translating the code, I am trying to turn on and off the image when the pin state changes:
Example:
When pin A2 on my MEGA goes high (+5vdc) I want my SD to spool up and load an image so here is my code snipit:
****myFiles.load(20, 55, 130, 130, "Power Medium.raw");****
So now when the pin state changes back to low (0vdc), how do I remove the image without clearing the entire screen? The image seems to stay frozen instead of disappearing when the pin voltage falls away.
Any ideas? I am stumped. Thanks in advance for any comments and suggestions that may help me over the hump.

user4143: It's quite silmple: just draw a box over the image the same colour as the background.
Either that or draw a different image over the top of the existing image.
