There is a valid question there at the end that is not out of topic,
[does] The use of a single image for several logos and icons … impacts the accessibility of the website
If you have individual images and multiple HTTP requests or only one sprite image has zero affect accessibility.
How The use of the image (either one or more) is what affects accessibility.
Images that are used in the background (CSS
Background: url (foo.jpg) with offsets) are invisible to screen readers, which is good Yes The image is decorative.
If a background image is informative and has a meaning, then that meaning must be conveyed to all users. That is usually done with the
alt attribute in the
label, but if the image is in the background, then the image information should be in the html element that it contains (or one of its ancestors).
But this is beginning to be implemented and should be dealt with at stackoverflow.com. You can post there and use the
accessibility Label as you did in this question.
The simple answer to the question collected is "no".
