Selling photo prints in different sizes.

The company that I am designing the website for sells photo prints. The photos are available for purchase in 5 sizes:

5 X 7 - $13.95
8 X 10 - $15.95
11 X 14 - $17.95
11 X 17 - $19.95
12 X 18 - $21.95

Would someone be able to tell me step by step how to make these options on each photo with the different prices as I add each product (image) to the cart? Thanks.

etc.

Make Product ...
Product Price: 0.00
Priced by Attribute: YES

Attributes Controller ..
Option Name: Photo Size
Option Value: pick from the list of sizes you made
Prefix: blank
Price: enter price

Repeat until done

Thank you.

I should have mentioned this previously, but I am new to zen cart. Where is the Make Product option?

First you make Categories ... then you make Products ...

Admin ... Catalog ... Categories/Products ...

Thanks again...

Now I dont see the Priced by Attribute option. Is there something I am supposed to do to get that to show up?

Are you adding the Product as Product General?

If so ... it is on the screen:

Product is Free: Yes No
Product is Call for Price: Yes No
Product Priced by Attributes: Yes No

Use the add-on for Gallery and you will be able to load up multiple products at one time. You will have to use Zencart v1.2.7 - they work beautifully together. More info here: http://codex.gallery2.org/index.php/Gallery2:Modules:zencart
