Iirc, the maximum uncompressed size for an image in plucker is 60k
(64k minus a safety margin).
But a 400x400 image in 8bpp would be up to 156k, so it would never be
displayable. Earlier versions of the viewer crashed when given too
large images, in newer versions the python-code might already detect
too large images and leave them out of the plucker file.
Try a far smaller maximum size or fewer colors (4bit gray with
Floyd-Steinberg-Dithering is usually appropriate to view enough detail
on images.)
400x300 in 4bit is about maximum, being 60000 Bytes, or about 58.5k
To view bigger images you probably need a specialized image viewer.
