I need some help, and before we get going, I know it is probably not best practice, but I am doing some maintenance to an existing site and need to accomplish the following for a fix.

<a rel="lightbox" href="site.com" title="a generated title"><img src="site.com/img" class="post-image" alt="a long description"/></a>

Okay, so I am trying to figure out how to use jQuery or any other method to take the "alt" attribute from my image, and dynamically overwrite the "title" attribute of my "a" tag.

Any help would be awesome, I am kinda lost at this juncture.
