5 years ago I did a bit a research and found the following, tested with sampling the result on docs and documentation, png files only (jpg accordingly)
First of all, checking if any png files would contain upper case characters
starting directory docs/modules
find ./ -type f \( -iname \*.png \) | grep -v "[a-z]"
(no result, good)Find the location(s) of the file (to check single files found from below...)
Example
find ./ -type f \( -iname \023-ucs-owncloud-apps.png \)
./administration_manual/assets/images/appliance/ucs/onlyoffice/023-ucs-owncloud-apps.png
./administration_manual/pages/images/appliance/ucs/onlyoffice/023-ucs-owncloud-apps.pngadministration_manual
find /var/www/owncloud/docs/modules/administration_manual/assets -name '*.png' |
awk -F/ '{print tolower($NF)}' |
sort -u > /tmp/png-files &&
grep -IhFriof /tmp/png-files --exclude-dir="assets" . |
awk '{print tolower($0)}' | sort -u | comm -23 /tmp/png-files -023-ucs-owncloud-apps.png

@settermjd As the topic tells, is there a automatism available to identify all those images in docs which are nowhere used?
