Create and send thumbnail when sending an image
Riot (and Neo) send a thumbnail with every image, max 800x600 in size, uploaded separately, and then included in the m.image
event, under info
like so:
"info" : {
"thumbnail_url": "mxc://matrix.org/yFwVgCaXXsgCcofJZIquxPYp",
"thumbnail_info": {
"w": (width),
"h": (height),
"mimetype": (mime)
}
}
Would be nice if Fractal sent that as well
