Product Listing Enhancements, Thumbnails & Manufacturer Headings V1.txt
This contribution is a much changed version of Product Thumbnail Listing that I started only a short while ago, but as thumbnails is now only one part I felt it should be a new contribution.
I was requested to make a contribution to Group Product Listing By Manufacturer with a manufacturer short description. This does exactly that based around the original product listing, so the old admin controls apply along with some new ones.
The thumbnails part displays products with thumbnail images in a grid layout, you define how many boxes per line plus image & box sizes. It shows the product image in a box with product name, price, short description (if you have that) & buy now or details button. This also supports Additional Images (http://addons.oscommerce.com/info/1032) If you have this it will select the medium size image if it exists.
The customer can switch between thumbnails & manufacturer if you set default to either. If you change default you must select a new category to reset your display.
During writing I cam accross some bugs in the core code details & fixes are at the bottom of the installation notes.
Extra setting are added to admin:
Additionally existing settings controling the display of Product Name & Price Are Honored.
The database query used is unchanged from the original, so order you set in admin etc will apply as before.
The style of the display is controlled by a new entry in your css, you can set there if you wish a background image, colours, borders etc.
Page views are included in the package so you can see the result.

Product Listing Enhancements, Thumbnails & Manufacturer Headings V1.1
Some have reported first upload (V1) corrupted!
V1.1 Modified code if manufacture list is selected, but no manufacturers exist for category, the display will revert to standard listing rather than show blank display.
Some poeple have had setup errors, so I`ve added a debug option, if you have any trouble, find at the start of product_listing.php
$debug = 'no'; change this to $debug = 'yes'; then report the alert message in the forum.
