Multiple sizes and attributes for shipping

Hello

Client is a photographer.

Site is built using ZenCart 1.38 and Gallery2 using Gallery bridge. Shipping is using the Aust Post module.

Photos are uploaded using Gallery2.

Each photo has different sizes

• 6x4
• 7x5
• 6x5
• 8x10
• 8x12 (A4)
• 29x40 (A3)
• 42x60 (A2)
• 60x80 (A1)and each size has a different weight in kilograms.

In order to calculate the shipping correctly I want to be able to specify a size and weight for each attribute

eg a 6x4 photo has a size of 15.2cm x 10.2 cm x 0.5cm and an approx weight of 0.25 kgs

where a 8x12 photo has a size of 20.3cm x 30.5cm x 0.5cm and an approx weight of 0.75 kgs

I want to be able to set this generically, without having to do this on a per item basis.

I would also like it to be applied whenever new photos are added via Gallery, without the client having to globally reapply the settings (client not very shopping cart savvy :blush:)

Is there any way to do this?

Regards
Danielle
