I'm trying to follow the tutorial here: https://www.zen-cart.com/tutorials/index.php?article=58

Specifically I am here:
From the Admin, you edit a product and specify an image file called:
a_bugs_life.gif
and put it in the
/images/dvd directory via the drop down.

Now you use your FTP program to upload additional images to /images/dvd
I opened my product listing, added the image, clicked the dvd option from the dropdown, and updated it. What I don't understand is where I would now FTP the additional image. Do I first need to create a subfolder under images titles dvd and put them there?
