Listing attached documents in a custom block

Here's how to create a custom block that does the following:

1. Hide the default attachments list at the bottom of nodes.
2. Add a custom block that automatically shows whenever a node contains attachments.
3. Add file type images.

Directions

Create a custom block, and place the following code in the block body field. Be sure to use the PHP Input Filter.

 * if (arg(0) == 'node' && is_numeric(arg(1))) {
 *       $node = node_load(arg(1));
 *        print theme('upload_attachments', $node->files, true);
 * }

Place the following code in template.php

/**
 * Displays file attachments in a block
 * Replaces default theme in upload.module.
 * Moves the display to a block. Must be called within a block using the following code:
 * (Include PHP tags!
 *
 * if (arg(0) == 'node' && is_numeric(arg(1))) {
 *       $node = node_load(arg(1));
 *        print theme('upload_attachments', $node->files, true);
 * }
 *
