App Model "Image" conflicts with RMagick "Image"

(3) Somehow explicitly refer to my Image model using some foolproof

Rails application's models are all in? Basically: is there any way at
all to refer to my Image model without relying upon it to be in Ruby's
top-level symbol table?

Seems like I ran into something like this before. Will

image = ::Image.find(params[:id])

work? Seems like it should.
