OTTO rule
OTTO images must be 500 x 1000 px minimum and 4500 px maximum per side
OTTO requires a minimum of 500 x 1000 px and caps the longest side at 4500 px so images stay within the catalog's display and zoom bounds.

What we check
CatalogPrep reads the image dimensions and flags images below the 500 x 1000 px minimum or above the 4500 px per-side maximum.
How to fix
Resize to meet the minimum and downscale anything over 4500 px. CatalogPrep applies the resize automatically.
