Ok I know that Zen Cart supports sm/med/lrg image sizes for products, but I've seen differing explanations of how to do it.

One is to use different folders (medium, large, and I guess the product folder is where the small one goes? Let me know).

One is to use _MED and _LRG suffixes to the filenames.

I tried the different folders, though I had also added the suffixes... anyway it didn't work. Neither did putting all the files with suffixes in the same folder.

Am I supposed to put the images with the same filenames (no suffixes) in the different folders by size?

What is the final, real answer here? I'm confused

Thanks in advance for your help!

(Oh, and does the same apply for the additional product images? (_01, _02, etc)?
