I've decided to stress test this idea. This is what google errors on:

"It's taking a while to calculate formulas. More results may appear shortly."

I set the spreadsheet document to load images like so: =image("http://example.com/image?id=146&r={increment here}")

After 30 or so images, google starts to slow down its fetch rate.

Multiple spreadsheets ?

30 per spreadsheet it would seem. It seems to be that if the document takes longer then 2 seconds to load, it starts limiting itself.
