@foone as long as you can post-edit, e.g., the alt-text field on the toot.
One might use the same picture for different purposes and need to emphasize different aspect.
(e.g. I don't give a damn what color cat's fur is, but the air of contempt on the cat's face is super important), specially if you follow the "how you would describe it to a friend ovee the phone" style of alt+text.
@foone I stick ALT text in the file metadata of my JPEGs but most software just strips it unused.
@foone I want a camera app with voice annotation. Preferably with automated voice to text
@cliffordheath that'd be cool!
@foone It may on balance be worthwhile, though for many or most alt text uses a singular description of an image is not as useful as one might think—it’s almost always really critical to describe an image based on the purpose you intend for it rather then a detailed description—otherwise the description is just too long and full of pointless detail.
Still, sometimes this would be excellent, like for reusable memes and such where the essentials are what matters and reuse is common!
All the popular stable diffusion front ends put the input prompt in a text block in the output image.
This blog post describes a plant for better accessibility in GNOME and proposes standardizing a form of structured image descriptions for screenshots. Kinda cool!

@foone yep. it exists. I typically use XMP metadata during image processing jobs, which has a text field for 'description' and many others. it's fairly standard for XMP tooling to be included in the app's base features.

@foone i've actually been doing exactly this with my images for a while now using exiftool -Description
the stored descriptions are displayed in the inspector window when i open my images in preview.app, but barely anything else seems to be aware of it, so it's probably not a standardised thing to do
@foone They wouldn't be as durable as you'd hope. So many sites strip EXIF anyway to remove GeoIP, and descriptions would probably get stripped too since I'm sure there would be a lot of "Picture I took of my beautiful daughter Jane Smith, SSN 123-45-6789, as we sit on the lawn in front of our house at 123 Main Street".
@foone I'd like more than one such field, one is describing what the image is of, for those who can't see it, the other is explaining the context of the picture, for everyone
@foone It appears it’s already part of the PNG spec. https://www.w3.org/TR/png/#11textinfo
@foone I'd love this, it would be like being able to write a description on the back of a physical photograph
@foone I wonder if anyone has thought of repacking PNG's to WEBP or just ban them.
@foone Accessibility description, you mean?
I wonder if anyone has proposed a PNG/EXIF extension to let you embed an image description in an image file. It'd live with the image so as you upload it to different sites, the description stays with it
