Slice your image using our friendly FAQ page. On the command line this is:.

convert whole.png -crop 10x10 -set filename:a "row%Y col%X" '%[filename:a].png'

You'll need to convert each 10×10 image to a 600-byte hexadecimal RGB string. Here is the command for that:

convert part.png rgb:- | hexdump -v -e '/1 "%02X"' | sed -e 's/^/0x'

But instead you want a batch command, here it is:

for a in row*col*png; do echo -n "$a\t0x"; convert $a rgb:- | hexdump -v -e '/1 "%02X"'; echo; done

Next, use Excel or similar and create columns: Square number, Title, URL, ImageHexData. Fill in one row per customization and the ImageHexData is the result of the command above, run for each image.

As yet we do not have advice on how many personalizations you can do at once.
