How can I create category links with pictures in the main section of the home page? The category links are currently in the left column with no pictures. That is fine for other pages in the cart, but the home page should have the categories in main section.

This contribution should do it.

Most of the product pictures are very bad unless they are clicked on and enlarged. After reading some posts on your blog, I think this is because we don't have the correct thumbnail versions of the pictures.

That is the exact reason - osCommerce just compacts the large image using width and height attributes - making them look awful when small thumbnail.

I downloaded your Club osCommerce Easy Thumbnail contribution, but I am not sure if I can use it because our shopping cart is not unmodified. Can I still use it?

You can use the large/small image mod I made, you would need to incorporate the code changes into your own files - the best way to do this is to use a program called "Beyond Compare". I also offer an install service should that be of help - it doesn't matter how much you've changed your files, I'll make it fit - email me if you need me to give you a price for this.

Good luck! Gary
