Use an IA API as an option to automatically describe embedded images on message

[Askthedust84]

Pitch

Someone mentionned this one that an mastodon web client already uses (https://mstdn.fr/@ButterflyOfFire/113933318525233468) :

Motivation

Many people forget to describe the images due to lack of knowledge, time or simply willpower. This would be of great benefit to the blind on the fedivers.
