This one is hard to formulate... trying to get some new (hopefully useful) ideas in.
Snag.gy (and others) offer free image hosting (time limited) with related url.
Pasting a link to hosted image to Cintanotes is no problem.
What would be fun is to have an integrated image service via Cintanotes for a basic free, premium and perhaps (even better) a one-time fee (just like the app).
Of course, Cintanotes would have to incorporate screenshot capabilities.
