Human readable image's alt and titles atributes

Hi,

My current devs integrates accessibility requirements, and it seems there was some kind of anomaly in the generated images's ALT and TITLE output. Imagecache writes a raw $alt ant $title format, transforming any HTML tags to 'non-human' plain text.

Below is what I modified to obtain user-friendly ALTs and TITLEs.
In imagecache.module at line 893 locate :

$ours = array(
    'src' => imagecache_create_url($presetname, $path, FALSE, $absolute),
    'alt' => $alt,
    'title' => $title,
  );

Then replace it with the following :

$ours = array(
    'src' => imagecache_create_url($presetname, $path, FALSE, $absolute),
    'alt' => trim(substr(strip_tags($alt), 0, 74)),
    'title' => strip_tags($title),
  );

Might not be the best solution, but it's working in my case.

Cheers,

David.
