i don't remember: has there been discussions about making gnusocial automatically create attachments/thumbnails from any links to images?
-
that would at the same time make attachments federate.
-
-
it could be a plugin, if site admins don't want their servers to fill upp with remote images
-
as far as i can understand, downloading remote images and creating a local thumbnails would be reasonably secure, >

-
@hannes2peer making the local instance create & store thumbnails locally might be a bulletproof way—unless disk space gets tight

@hannes2peer thumbnails for remote image attachments (AND #youtube previews, worked in SN but currently broken) would be #great #GNUsocialUI
-
@mcscx oh, so maybe it's an easy fix then
-
@hannes2peer [I'm talking abt ClassicUI] Remote thumbnails were working before btwn certain instances. E.g. quit.im previews in Quitter.se
-
@mcscx quit.im is a special case since it embeds the image in the rendered html, which is considered unsafe in newer gnusocial, i think
-
@hannes2peer it also worked/works btwn certain other instances, e.g. loadaverage previews were visible on @atarifrosch's old instance, iirc

@hannes2peer …or the other way round. I don't recall exactly.
-
@hannes2peer I think @yvolk aka @andstatus had an idea why previews of remote image attachments sometimes don't work in the GNUsocial web ui

I remember we investigated the issue: Attachments (as a separate metadata with links to images... in…

On my old SN instance I could see attachements and YT video previews, yes. Would be great if this worked here on GS, too.

@hannes2peer imho <no expert> thumbnails in remote posts could work without federating the actual thumbnail files.
-
@mcscx i guess, but since some intances are non-https that would make users on https do non-http requests, which browsers complain about
-
@hannes2peer Images can be proxied in the same fashion as it's done in Red Matrix.
