wp_get_attachment_image not working as expected

[ramaboo]

Assume the following bit of code:

wp_get_attachment_image(1, 'thumbnail', false, array('title' => 'fobar'));

It will produce something like this:
<img width="150" height="150" src="​http://testcrave.genome.ramaboo.com/wp-content/uploads/2011/10/DC040811-RW23-150x150.jpg" class="attachment-thumbnail" alt="DC040811 RW23 150x150 gallery" title="foobar" />

as expected!

Now try this:
wp_get_attachment_image(1, 'thumbnail', false, array('alt' => 'fobar'));

and the result is:
<img width="150" height="150" src="​http://testcrave.genome.ramaboo.com/wp-content/uploads/2011/10/DC040811-RW23-150x150.jpg" class="attachment-thumbnail" alt="DC040811 RW23 150x150 gallery" title="DC040811-RW23" />

I would expect it to honor the alt attribute but instead the system uses the default alt attribute. According to the documentation ​http://codex.wordpress.org/Function_Reference/wp_get_attachment_image passing in array('alt' => 'foobar') for $attr should be valid.

I also tried it with array('class' => 'foobar') and array('foo' => 'foobar') and both worked as expected. The only one I have found that does not work is array('alt' => 'foobar').

I've checked this on 3.2.1 and 3.3-beta2, and the alt attribute is changed accordingly.

Could you please provide steps to reproduce this on a clean install?

You correct it works on a vanilla install. Must have been a plugin that somehow messed it up because it's not working on the live site I have.
