Or drop down just a step to just use NSBitmapImageRep instead of
NSImage which avoids all the caching issues (since you never make an

representationUsingType: properties: to get the data for a JPG or PNG
file anyway).
I am not using NSImage - except to draw an existing file into my
premade
NSBitmapImageRep. Is there a way to draw a jpg into this
NSBitmapRep without
loading the jpg into an NSImage?
Yes - NSBitmapImageRep's can be init'ed with NSData (the contents of
a jpg) and being a subclass of NSImageRep, can be drawn using
drawAtPoint or drawInRect.
