Okay, here's a patch to fix the theme_image attribute problem.


I've also added a handler so that attributes can either be a string (as
they were in the past - although it wasn't working) or an associative
array.


I've marked this issue as critical because the current version of
theme_image() does not accept attributes at all.

Here's the theme_image function from theme.inc



<?php
 function theme_image($path, $alt = '', $title = '', $attr = '',
$getsize = true) {
  if (!$getsize || (file_exists($path) && (list($width, $height,
$type, $attr) = @getimagesize($path)))) {
    return "<img src=\"$path\" $attr alt=\"$alt\" title=\"$title\"
/>";
  }
} 
?>




Any arguments sent to the function for $attr get clobbered by the
getimagesize() call. And $getsize defaults to true, so in a call to:



<?php
 theme_image('files/images/foo', 'alt_text', 'title_text',
'align="left"') 
?>




the 'align="left"' never makes it to the page. The two attribute values
really should be able to coexist, allowing for both getsize attributes
and additional 'argumented' attributes as well.


I recommend changing the $attr in the second line to $imgattr, then
adding $imgattr to the tag returned in the third.
