TLDR; If you don’t add alt text to your LinkedIn images, the default will not be blank, but will call you out to visually impaired users.
I was looking at some company posts, and before I share them, I check to make sure that whoever posted them added the tags. I checked the view-source and was surprised to find that defail alt text, instead of being blank, was “No alternative text description for this image”.
Now, sometimes a blank alt text is perfectly acceptable (See W3C alt decision tree). The VIP (visually impaired person) would just go on, and hopefully the context or the post would contain all the necessary info.
But LinkedIn, instead of leaving it blank, tells them you just didn’t think about it!
Fix your alt tag
Now, just because you forgot, it’s easy to go back and edit that – you can fix the alt text.
1. Go to your post, and click edit
2. In the top corner of your image, click edit
3. Fix your alt tag – make it blank if it’s a decorative non essential image and all text is contained in the post.
If there is a lot of text in the image, here’s a shortcut -save the image and upload to https://www.imagetotext.info/ to get the text from the image. Be sure to add any descriptive text to add the context of why you put the image up there in the first place!
