Several contributions have been created to allow for different sizes/thumbnails of product images. These have all seemed to create tremendous amounts of extra labor especially when several hundreds or even thousands of product images are needed.
What this contribution does is to allow you to have a single large product image that is dynamically resized on your website prior to downloading to the visitor. Why download a 2-3Mb picture when only a 3-4K thumbnail is needed or have 3 different sizes when only one is needed.
This contribution is written to work with all osCommerce 2.x versions and with only a single change to be compatible with osCommerce 3.0.
