The alt text should work as a single sentence/paragraph that can be replaced for the image, convey the same content and still make sense in the context of the adjacent content.
For the blind, the image effectively doesn't exist, all that there is is the text. You should not make the visually impaired user understand what the image is all about. It would be nice if the title attribute on the accept this answer graphic would say something like " click to accept this answer" if the answer wasn't accepted and " Click to remove this answer as the accepted answer" if it is the accepted answer. For example the reason my accepted answer rate is so low is because I have no way of telling whether I have accepted an answer on a question. An example of something that could be useful is additional information.
My screen reader doesn't read them by default so I don't normally use them. Neither of the tags are descriptive, the favorite tag is just " *" and the accept the answer tag is " check" The only way for me to tell what they are is to read the source or have someone sighted let me know what they are for.Īs far as title attributes go I don't really have much advice. Examples of bad alt tags are the make this question a favorite and accept this answer. For example, Stack Overflow's alt tags for the vote up and vote down options are nice since they don't take long to read and get to the point quickly. I'm a screen reader user and will use Stack Overflow as an example of both the good and bad.Īlt tags should be brief and descriptive.
