IMG with null ALT and non-null TITLE attributes Screen reader compatibility

Last updated: October 16, 2016

Expected Result: causes problems in some screen readers

Actual Result: causes problems in 13 screen reader / browser combinations

For expected failures, the results show which AT combos the failures affect. Results are recorded from the user's viewpoint, so describe the user impact of authoring errors.

Author intent is unclear in this markup since ALT='' marks image as presentational, but TITLE attribute gives it an accessible name.

Code used for this test:


        <img src='1234.png' alt='' title='This is the title attribute'>

Test notes

All tests were carried out with screen reader factory settings. JAWS in particular has a wide variety of settings controlling exactly what gets spoken.

Screen readers allow users to interact in different modes, and can produce very different results in each mode. The modes used in these tests are:
