[Image-SIG] Mutable images

[Laura & Edward Cannon]

Something that would be simple would be a wrapper class containing an
image as an attribute. You could reference the wrapper instead of the
image itself, which would solve your problem. I think you could write
a wrapper in 20-30 lines of code, and probably have a very small
performance hit if any.
