Adobe has just added AltText & Extended Description to the IPTC fields supported by Lightroom Classic (I requested this feature in March 2022 & just got word that they've added it). This is potentially huge for anyone who uses LR to prep images for social media, e.g. Mastodon, or the Web.
@paul Could Ivory automatically read these fields & use them to populate the alt-text on image posts? (Read Ext. Desc. first, fallback to AltText?)
