Image3 doesn't work on my platform, but inspecting the source reveals that
write_image is actually an adverb, not a verb (I find this strange). For
your purposes, you could probably write a verbal wrapper like so:
wi =: 4 : 'x write_image y'
and then use it in place of write_image
(('small/'&, wi~ ((3 3)&resize_image)@:read_image)@:>) i
Again, image3 doesn't run on my system, so this is plausible but untested.
