for google only
i use google photos and found a work around for the posting issues.
if there is a 'share' link, that i copy and paste to another link that makes the code work.
here is the google photo converter link:
https://ctrlq.org/google/photos/
so,
copy the picture share link, paste it in the converter. that app makes a useable link that works with skoolie's insert photo button.
