I don’t want to boost inaccessible images that don’t have a caption. But I don’t use a screen reader, so it’s been hard to know. Only the MetaText app shows text captions. Or so I thought.
I just accidentally discovered that if you click-and-hold on an image in desktop-Mastodon, you can see if there’s a caption. Requires an active extra step, but at least it’s there.
Sharing in case I’m not the only one who didn’t know this.
An article on how to write an effective #AltText #ImageDescription for #accessibility...
MAIN POINTS:
• describe the image only, not the photographer credits or keywords
• write a description appropriate to the context (ex., a post about photography vs. a celebrity)
• make it as concise as possible, except if you are transcribing text in an image
• no need to start with "An image of..." as the screen reader says that by default
• end with a period to provide a pause
This post contains everything you need to know about alt-texts! When to use them and how to perfectly craft them. By me, Daniel, a web developer with vision impairment who use a screen reader in my day-to-day life.Daniel Göransson (Axess Lab)
I'm not blind or have impaired vision, so take this with a grain of salt (feel free to correct me), but people who put nondescript one sentence alt texts are almost worse than those who put no alt text.
At least if I'm about to boost a picture without, glitch-soc will warn me about it. If a picture has an alt text like "screenshot of my tweet", that's less than useless but it will slip through the alt text detector.
Write good alt text ffs. Describe the picture. Not a title or a TLDR, a proper description. If it's text, copy the text into the image description. If it's selfies, don't write "a selfie of me", describe your selfies. Describe film scenes, descripe paintings, descripe charts and infographics. You have, on this instance at least, 1500 characters to describe your pictures. Do it.
And if 1500 isn't enough, you can add a second picture to keep describing it.

The official Mastodon app seems to have a bug when posting an image. Sometimes it will let you compose the post but when you add the image, the Publish button is greyed out. There are other apps that are good, for example, Metatext and Toot! on iOS, and Tusky on Android.
-----------------------------------------------------
There is an Advanced web interface that looks like Tweetdeck. You can enable it in Settings, Appearance.
-----------------------------------------------------
Putting plain text into the 'Search or paste URL' box at the top left of the web interface shows results from your own posts or posts that you have boosted, favourited, or been mentioned in. You can also search for user names, display names, and hashtags located in the body of posts. Putting a hashtag into a Content Warning doesn't work. It won't be clickable and might not be searchable unless someone else has used it in the body of a post.
-----------------------------------------------------
If you find a post on another Mastodon instance and want to boost it on your own instance, click the … menu and then Copy Link. Go back to your own instance, paste the link into the Search box and press Enter. The post will appear below the Search box, and you can boost it from there.
-----------------------------------------------------
You can create Filters to block posts containing certain pieces of text from being displayed in your Home feed. If you want, the filter can hide the post behind a Content Warning so that you can decide whether to view it or not.
-----------------------------------------------------
In the Advanced web interface, you can search for a hashtag, click the result and it will appear in its own column. You can then click the column settings icon at the top right and Pin the column. You can add more tags to the same column, if you like.
-----------------------------------------------------
If you boost a post and the author edits it, you will get a notification so that you know that it has been edited.
-----------------------------------------------------
It's the custom on Mastodon that if you're posting about Mastodon itself, you put a context warning (CW) of "Meta" so that people's timelines aren't flooded with things they don't want or need to see. Likewise, posts about Twitter can be hidden behind a CW: Twitter (or birdsite, birbsite, hellsite, tw). "CW: meta, bird" should be an obvious one.
-----------------------------------------------------
When you're writing hashtags that are a combination of several words, please use "camel case" (#CamelCase) so that screenreaders used by people with impaired vision can pronounce them properly.
-----------------------------------------------------
Mastodon has its own thread unroller: mastodon.social/@threadunrolle…
-----------------------------------------------------
If you go into Settings in Mastodon's web interface and click on Other, you'll see a list of languages at the bottom which you can use to control which posts you'll see.
This works well if you select which language your own posts are in. If you make a post in a different language from your default, select that language using the button at the bottom of the edit box before you post. This way, it can be filtered out on other people's feeds if they choose not to see posts in that language.
-----------------------------------------------------
When posting images, please add Alt Text. This allows sight-impaired people using screenreaders to know what is in the pictures. Let's keep the Fediverse friendly to everyone.
-----------------------------------------------------
Please use a strong password to log in to your server. If you haven't already done so, make sure you have activated 2-Factor Authentication (2FA) in your Settings. This will keep you and everyone else safe. There are a number of good 2FA apps available in the Apple and Google app stores. In fact, iCloud Keychain on an Apple device can be used to generate 2FA keys. See this article for details: appleinsider.com/inside/icloud…

You can balance both account security with the convenience of autofill when you set up two-factor authentication in iCloud Keychain. Here's how to do it.Darryl Boxberger (AppleInsider)
