WordPress Codex: Displaying all post attachment in thumbnails on an archive page

I’m putting the final touch on this photographer portfolio website built with WordPress.

Here’s the development link: http://dev.manifold.ws/maudearsenault/category/fashion/ (NSFW)

I’m using post categories for the main navigation (Fashion, Beauty, Lifestyle…).
On the category page, I figured out how to have two different views of the posts: the default view shows the pictures at 600px height in a horizontal scroll layout while the alternate view (which you can access by clicking the “view all” link) displays a grid of all the pictures in small thumbnail size.

I’m using the following code to display these small thumbnails:

<?php $images =& get_children( 'post_type=attachment&post_mime_type=image&post_parent=' . $post->ID );
foreach( $images as $imageID => $imagePost )
echo wp_get_attachment_link($imageID, 'thumbnail', false); ?>

While it displays the thumbnails the way I want it to, I have 2 problems with this code:

1. When I click on a thumbnail, it links to the picture file. I would like the thumbnails to link either to the category page with an anchor to the parent post OR to the post page if the first link isn’t possible.

2. Right now, the thumbnail titles (or perhaps it’s the link titles) are the name of the attachment files. I would rather the title be the title of the picture that I set in WordPress.

I’ve been messing around trying to make this work, looking through the WordPress Codex but couldn’t make it work.

Any help would be appreciated.

Thanks!
