One thing you might want to consider is putting the image data into fields
as opposed to custom properties, the reason being that field contents are
encrypted along with the rest of the stack data when a stack is password
protected, while custom props are not.  You can still display images from
the fields' contents, and the fields themselves cannot be cut and pasted.

I don't know who you audience is but I would guess the likelihood of your
users owning a copy of Rev is lower than folks' ability to snoop around file
contents.
