Hi! i am new to programming and would appreciate it if anyone could help.
This is the issue: I want to load different images to my 7 inch TFT LCD screen (sdd1963 based) from an SD Card and I'm not able to do it. I'm using the cold tears CTE Shield for Mega. This is the code I'm using:

However, i keep on getting an error during compilation as follow:

Would any1 be kind enough to help as i am running short on time.
Thanks in advance.
I think 'somebody' has made a right mess of that sketch!! Where did you get it from??
