  • (2022-08-18) Richard Graves: This tool did not work me. It correctly identified the alt text for the images on a page and for some of the icons, but not all of the icons. We tried a different tool and it had similar issues. After trying different approaches to expose the alt text for the icons in question, we tested with an iphone in voiceover mode and found that everything was done properly and was working correctly all along. The only issue was with the test tool(s). It was a challenge for me to navigate with voiceover on, but i learned that if I first navigate to the page to be tested, I could then use siri to turn voiceover on to test the images and icons on the page.
  • (2021-12-29) Lucas Tonin: works great, love it! can you add a option for a shortcut key to trigger the extension? so to trigger on and off quickly
  • (2021-03-06) Lin Rogers: have to click the extension to turn it on, which is annoying since i thought it was just adding a behavior to when hovering over images and i thought it was broken at first, and then it gives a popup of how many images there were, which usually covers up the image i was going to check. I have to reload it if i scroll too far down somewhere

  • (2020-09-10) Luis Moreno: No sirve
  • (2020-08-29) Fergus Murray: This just doesn't seem to work at all?
  • (2020-06-27) Michael Panagos: This doesn't seem to work any longer.
  • (2020-01-08) Sue Mullen: Interprets "" as missing alt text, when it is not missing, it is "".
  • (2020-01-06) Makoto Hirata: Perfect experience
  • (2019-11-16) Evan Henry: Nothing. Didn't work on any website.
  • (2019-11-15) Cameron Fife: It is useful, but I don't think it's ideal. For one, it breaks my javascript framework each time I run it (requiring me to force a refresh after activating the extension). The other problem is that I would prefer if this extension could essentially be turned on once and then keep using until it's turned off. I don't like having to keep turning it on after going through each page in my site.
  • (2019-08-26) Katelyn Howard: Can't use it in conjunction with "ContentBlockHelper". i wouldn't know what to whitelist to make the alt text appear on mouse hover, so it's just not usable for me (but works with CBH disabled, so i gave it 3 stars)
  • (2019-07-03) tejal tiwary: i found that it only shows alternate text if its define in html alt tag. It would be more helpful if alternat text of an image is generated automatically even if alt attribute is not given. Auto Alt text extension also has limitations
  • (2019-04-10) Efraín GB: No me sirvió. Nunca mostró un alt
  • (2019-03-13) Kai Cheng Ho: Easy to use!
  • (2019-01-30) Mark Owen: Requires jQuery and errors on sites without it
  • (2019-01-10) Key Chain: Very helpful and easy to use, thank you! Personally would not by default display the black window with all the links at the beginning. Would hide it, but allow to open in by clicking an icon. Still a great tool!
  • (2018-11-14) Rob Harvey: Great tool....proof by demonstration...gold standard...I use it to verify the findings of scanners
  • (2018-11-10) Does nothing. No alt tags are visible, no red or green marquee on hover is visible. (Using latest version of Chrome 70.0.3538.77 (Official build) (64-bits) for Mac.
  • (2018-08-10) Mr. Lance E Sloan (UMich): It's awkward. I thought it would make the value of "alt" properties show when hovering over images, just as it does with the values of "title". However, the "alt" values only show when the extension's overlay is activated, which requires extra interaction with the extension.
  • (2018-07-24) Fred Tanner: worked great for me!
  • (2018-07-07) Stephen Skinner: didn't work for me
  • (2018-06-19) Ashley Walls: Like the extension, but there is some jittering on hover. Maybe make some options for text size on hover? The text is HUGE. And maybe some color options?
  • (2018-05-03) Gerald Zuckerwar: The only app I could find that shows alt text on hoover. Works great but you have to reload the page when you're done, somehow it screws up other javascript
  • (2017-08-15) sunil kumar Jaiswal: What a great extension you have made. thats what I was looking for.Thanks

  • (2016-06-12) Anish Mandal: Excellent job. If you add feature of copy the alt text by double clicking on the relative image. that will be much more beneficial.

  • (2018-02-28, v:1.3.2) Tara: Doesn't seem to work
    Hey! I'm using the tool to check over the images on my website and when I scroll over the images the cursor turns green and the box reads 'Let's check image alt text.' Nothing happens when I double click either, any ideas what's happening? Website for example is http://terryphotoco.com/peyto-lake-elopement-banff-national-park/ Thanks! Tara
  • (2016-06-12, v:1.2.2) Anish Mandal: Feature Request.
    If you add feature of copy the alt text by double clicking on the relative image. that will be much more beneficial and useful. and External Images should be optional and customizable. so that developer can set up the external Image found Feature according to relative website.
