[themes] Alt text with preg_replace for accessibility

[Ross Kendall]

Hi Mark,

You could try this:
<?php
$pattern = '/<img[^>]*?((alt="(.*?)".*?>)|>)/i';
$replacement = '(Image: $3)';
print preg_replace($pattern, $replacement, $content);
?>

However, I do not think this whole approach is needed.  Web users who
don't want to view images can disable them in their web browser - the
job of the web designer is to make sure that the website works well
either way.  When I'm working on a design I always test with CSS and
images disabled.

Cheers,
Ross.
