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 allows is 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.
I've tried to make this contribution as simple of a cut/paste operation as possible, and also make it portable to any version of osCommerce. If anyone encounters any problems let me know and I'll update the contrib as quickly as possible.
The only limitation discovered so far involves GIF and PNG images, sometimes during the resize process the optimized PNG image may actually be upto 3x's the original GIF image size. This is due to PNG's inherit lossless image quality, this is still be worked on and will be addressed in future versions. As of now, GIF and PNG images are not optimized but it is coded to handle them if so desired.
PS: This is my first contribution, but won't be the last.
