Gentle reminder to add alt-text to your images and screenshots if you want your content to be accessible AND multiply your engagement with much more people reposting your posts.

Adding alt-text is a win-win-win situation, really. It helps everyone 💚

Doing alt-text is a lot more time consuming too, then no or few boosts occur anyways, so the principle of it and the practice itself becomes what is worthwhile, otherwise i would have stopped awhile ago.

@HeliosPi I think a lot of people simply do not know about this practice here (and need to be gently informed), and some organizations likely use applications to post the same content on various platforms at once, where adding alt-text isn't always doable or favoured.

@HeliosPi

Agreed. I'm also complaining that it takes a lot more time for me to post media with alt-text, proportionally, and doing so doesn't increase attention to that post.

@Aaron Caskey-Demaret

I agree. Alt text may be an amazing multiplier, but zero times anything is still zero 🙂

Sounds like me. My image posts have next to no audience.

Basically, I've got three kinds of image posts.

One, memes about the Fediverse. And I don't mean memes that treat the Fediverse as only Mastodon, or that make the Fediverse being Mastodon with a few things attached as add-ons being the unquestioned standard. I post them on @Jupiter's Fedi-Memes on (streams).

Two, memes about 3-D virtual worlds. I post these on @Jupiter Rowland's (streams) outlet.

Both of them are tricky in various ways. They only get one visual description each, and it goes into the alt-text. The tricky part here is that I no longer let my alt-texts grow longer than 512 characters. That's due to a bug on Misskey and its various forks and forks of forks (Sharkey, Iceshrimp-JS etc.): They only support alt-texts with up to 512 characters. They're supposed to truncate longer alt-texts, but instead, they delete longer alt-texts with no trace. So if you write an alt-text that's longer than 512 characters, someone on Misskey or Sharkey or so will think that you haven't written any alt-text at all.

In addition, I have to explain them which I do in the message text and not in the alt-text. My impression of especially Mastodon is that people love receiving explanations along with images that they don't understand right off the bat. I believe it has gotten to the point that these explanations are becoming or have since become almost as mandatory as visual descriptions. And both the Fediverse beyond Mastodon and 3-D virtual worlds are super-obscure topics that require explanations, not to mention that not everyone knows and understands all meme templates. So I have to explain my own image macros plus the topic they're about plus the meme templates I've used.

This is what really requires time and effort. That is, for the meme templates, I resort to links to KnowYourMeme. Some people on Mastodon are staunchly against links to explanations and demand that one explain everything right in the post. I've done that once. The result was six explanations with over 12,000 characters for one single meme template ("One Does Not Simply Walk Into Mordor"), and I haven't even explained The Lord of the Rings and its characters. I don't really think these people prefer 12,000 characters in one post to one link to KnowYourMeme, even if the two explanations for the topic took up another 12,000+ characters.

Well, and lastly, I sometimes post renderings from 3-D virtual worlds. I post these on @Jupiter Rowland's (streams) outlet, too. If I post them at all, for I haven't posted any in over two years.

That's because the effort is even bigger. Not only do I have to explain them, but I have to describe them twice. The image description in the alt-text is the short one. Again, no explanations, and this time, usually no text transcripts either. And then there's the long, fully detailed image description in the message text. It contains all explanations necessary, and it contains transcripts of any and all bits of text anywhere within the borders of the image, readable or not.

If I'm lucky, I don't have to write much more than 20,000 characters of descriptions, explanations and transcripts for one post. If I'm not so lucky, this block will exceed 60,000 characters and take two full days to research for and write for only one image.

I treat it like muscle, gotta keep my alt-text skills sharp cos one day someone might actually want to read my shitposts.

I actually try to optimise and improve my image descriptions further and further whenever I learn something new, e.g. new image-describing rules or guidelines. And I've learned enough about describing images and writing alt-texts specifically for the Fediverse that I've started putting together a wiki about that special topic.

Maybe I'll start following the advice from Veronica with Four Eyes and give two visual descriptions for each of my image, one in the alt-text, one in the message text for those who are visually impaired enough to not see my images clearly, but not so visually impaired that they require a screen reader to read the text on the screen.

Maybe I might go as far as describing my virtual world renderings three times so that there's an additional shorter description in the message text.

I mean, as you can probably tell from this comment, I don't have to worry about local character limits.
