We can't do much with pictures of code. Attach the actual code (hint -- it's a file whose extension is .vi).
Express VIs (such as the Vision Assistant) are fine for simple things, particularly if you have a good understanding of what you are doing. To do anything complex, you should learn how to work with the IMAQ functions directly.
Is there a particular Image you are studying? Along with the code, it doesn't hurt to attach some data.
