The size limit on patterned images was lifted in 2.7.x (I forget exactly
which version.) So Kevin was stating older restrictions. They still
apply on Mac OS though; only Mac OS X (and other platforms) can work
with any size image as a backpattern.

I did not mean to distinguish between Mac OS and Mac OS X, I am using
Mac OS rarely now, mostly for playing chess.
I see that the new docs of 2.7.4 state:
... in Revolution version 2.7, this restriction was partially lifted
and the engine will tile rectangular regions correctly with
arbitrarily sized background patterns.To be used on Windows and Unix
systems, height and width must be divisible by 8. To be used as a
fully cross-platform pattern, both an image's dimensions should be one
of 8, 16, 32, 64, or 128.
But the restrictions mentioned in the second sentence above about
divisibility by 8 and the dimensions do not apply here for my Windows
and Mac OS X computers. I just transferred a stack in both directions
with an backpattern image of 351X251, i.e.
1. I produced the tile in question with my "Seamless Tiles Generator" on
both platforms.
2. Put the 351X251 tile into a new stack on each platform and set the
backpattern of the card to it
3. Exchanged the stacks from Win to Mac and from Mac to Win
The result is identical, the backpatterns are displayed as expected
although they do not conform to the above stated restrictions.
The Mac-to-Windows stack produced with 2.7.4 can also be used in pre-2.7
versions (tested within the Metacard IDE 2.6.5) after the
stackfileversion is set to 2.4, meaning that the new - still
undocumented - format of backpatterns is also backwards compatible.
