http://www.w3.org/Bugs/Public/show_bug.cgi?id=14150 --- Comment #5 from html5bugs@gmail.com 2011-09-24 19:36:01 UTC --- This is what the current "best practices" are, which shows in the "real world" what people are doing in order to deal with the problem of alt hiding information and being "all but mandatory" while the title attribute does not hide information, but is meaningless to data gathering tools. This workaround is easy to do when generating code via program, but it is terrible. Once again, the inherent problem with the alt tag is that it tries to decide to hide or show the data it contains depending on whether the image is shown. There are very few, if any cases, where it can be proven that information given in an alt tag is absolutely meaningless to someone who can view the image (even a single, seemingly redundant, bit of text, can greatly clarify the contents of an image). As mentioned before, data which is available to the user regardless of whether the image is shown is infinitely better. <img src="http://l.yimg.com/bt/api/res/1.2/iZ5_LEa2m34dWe1zMfjvZA--/YXBwaWQ9eW5ld3M7Y2g9MzU0MDtjcj0xO2N3PTQ4MDA7ZHg9MDtkeT0wO2ZpPXVsY3JvcDtoPTE0MTtxPTg1O3c9MTkw/http://media.zenfs.com/en_us/News/ap_webfeeds/a8bdbdba7fc5b115f90e6a7067005814.jpg" width="190" height="141" alt="In this July 15, 2011 photo, atop roughly two miles of ice, technician Marie McLane launches a data-transmitting weather balloon at Summit Station, a remote research site operated by the U.S. National Science Foundation (NSF), and situated 10,500 feet above sea level, on top of the Greenland ice sheet. Climate scientists overwhelmingly agree that manmade greenhouse gases are warming the planet, accelerating the melt of Greenland's ice, and yet resistance to the idea appears to have hardened among many Americans.
