With the recent news that the r/blind community has migrated to a lemmy instance
[https://beehaw.org/post/672956], I thought now would be a good time to post a
quick PSA on image descriptions. Blind and low vision computer users often rely
on screen readers to navigate their computers and the internet. These tools work
great on text-based platforms (when the backend is coded correctly to make
buttons and UI elements visible to the screen reader), but they struggle a lot
with images. OCR and image recognition have come a long way, but they’re still
not reliable. On Lemmy, there’s no way (yet) to add alt text to image posts, but
one thing that we sighted folk can do to make the website a more accessible
place for the blind/low vision community is to describe the contents of the
image in text, so screen readers (or braille displays) can interpret the text
for the user. This doesn’t need to be anything fancy - you can see an example of
me doing so in this post here [https://beehaw.org/post/662902] - simply indicate
somewhere that you are describing the contents of the image, and then do so in
text. If you’re transcribing text, it’s best to do so as exact to the text in
the image as you can (including spelling errors!). If you’re describing
something visual, it’s best to keep it about the length of a tweet, but be as
detailed as you need to be to give context to what you write about in the post.
If you’d like a more detailed guide on how to best do image descriptions and alt
text, here’s a site that describes more specifics -

Edit: You are able to add alt text to embedded images, as noted by
@sal@mander.xyz here [https://beehaw.org/comment/384198]. This would only work
for images within the text of your comment, not for image posts (topics which
link to images). Edit 2: @retronautickz@beehaw.org
