OK. I've done some tests and included some screenshots.

With a Calibre-produced epub on a PocketBook 360 using the SonyReader output profile:-
  • The absolute maximum size I can get to display, without running off the edges, in AdobeViewer (ADE) is 363x469 pixels. If you want "rounder" numbers and a bit of leeway, then I guess 360x465 would be OK.

  • However, if viewing the same epub in FBReader, the standard SonyReader maximum image size of 590x775 displays with no problems and the 363x469 looks rather puny.
Neither of the 2 images is rescaled by the Calibre epub conversion.

The first two images compare ADE vs FBReader for a JPG image 363x469.

The last two images compare ADE vs FBReader for a JPG image 590x775.

P.S. Do you think this sounds like a bug in ADE and that I should raise it in the PocketBook forum?
