Mastodon users, new and old:

You can add a caption, or alt-text, to images you toot!

These captions make your toots more accessible, by giving people who can't see the image a description of what's in the image.

Just hover over the image over you attach it and type a description in the spot that says "Describe for the visually impaired" before you hit the TOOT! button.

Please also encourage Mastodon app authors to add caption functionality. And please boost. Thanks!

@zigg Absolutely behind you on this when it comes to photos, but what do you think about artworks? Does it really make sense to describe drawings and paintings, which really only exist to be seen?
Can a visually impaired person enjoy a written description of a painting or is it a vain effort?

@acrazymind I am not an expert on this topic by any means, but I would suggest a simple description (e.g. "a drawing of X") that would serve to remove doubt in the reader's mind that they are missing anything that they could appreciate.

I think that would be okay, though I would welcome the advice of someone with more experience here 🙂

@zigg Clarifying what it is is a good point, thanks.
Are you aware of any visually impaired users on here?

@acrazymind If they’re people I interact with, I’m not aware of them.

I did once work with a legally-blind man who used a screenreader to work extensively with Unix. The technology has improved considerably since then, I know.

Il faut aussi penser à celles et ceux qui "regardent" leur écran à l'aide d'un lecteur d'écran (synthèse vocale ou braille) et ne peuvent apprécier les images comme la plupart des "voyants".
Une description leur donne une idée de ce qui est censé illustrer l'article ou le message qu'ils lisent dans la mesure où les deux média, images et textes, sont complémentaires.

@zigg Out of curiosity, is this adding an aria-label to the image?

@PaulFerence I'm only seeing an alt attribute on the img in my inspector. I added a caption to the toot about how to caption

@Kit You mean captioning an image on mobile web?

I don't use it; I'm not sure how that would work. Can you tap the lower part of the image to add the caption?

@zigg This is great! (and I had no idea it was a thing we could do)

@zigg thanks zigg!

it works on mobile web too - just tap the bottom of the image and the input will appear!

I don't have more to say but feel the need for a third exclamation!

@zigg Thanks for pointing this out! This is very simple to do with the web client.

@zigg I use Mastolab, does it work there too? Cause I couldn't find it.
If not, any other app would you recomend for this?

@danielseda I heard Tusky is going to add it soon. You can also use the mobile web app.

I’m not aware of other apps supporting it at the moment.

Thanks, gonna keep an eye on it. I always add description at my birdsite posts and I couldn't do it here yet since I post mostly from Mastslab til now

@zigg This. Is. Awesome. My only complaint is that is ays "for the visually impaired" when actually accessible technology helps everyone.

@saradgore That’s a great point! I know I’m personally a regular user of both closed captioning and mouse-pointer magnification, and I don’t qualify as either deaf or blind.

@zigg Also the ability to tab through web pages and apps is considered an accessibility feature and I would be realllllly angry if a web page didn't have that.
