I'm trying to work with drawAtPoint and drawInRect to position and size the image(s) (there will be 1 to 6 of them, depending). The code I have is something like this:

-drawAtPoint: does not return any value, rather it takes action on the current context (which only exists if you explicitly push a current context or are inside of -drawRect:). So this line of code doesn't make a whole lot of sense :).
If you want to position an image view (presumably 'resultImage') then move it using the UIView 'center' or 'frame' property. There are a fair number of samples that show this (look up the properties on UIView in the documentation for links to the samples).
