TYPO3 Core

According to wcag (web content accesibility group) of the w3c it is not possible to have source like this

<a href='sss'><img src='xxxx' /></a>

It is necessary to have a meaningful text to describe the link or use a "d" and a longdesc url like

<a href='aaa'><img src='xxxx' />Click here for the fullsized picture "massaker on innocent karen children"</a>

<a href='aaa' longdesc='http:www.test.com/descriptionpicture.html><img src='xxxx' />d</a>

have no text at all is confusing for blind people

an additional element in

tt_content.image.20.1.imageLinkWrap

named imageLinkText or something like this is needed so
w3c wcag requirements are met

required changes around line 2699 of this class.tslib_content.php in sysext tslib

$a2= $conf['imageLinkText'] . '</a>';

instead of

$a2= '</a>';

in 2 places in the function
