So I have a price list set for all the photos in a gallery, however, I want to price certain images at specific prices other than the gallery prices. How can I do that?
First, since this requires multiple active pricelists you will need to have a Pro level account. Portfolio level accounts can only have a single active pricelist.
To apply a pricelist to a specific photo, open the pricelist. Select Edit List. You will see a box showing:
Click on the Single Photos box and you will then be able to select photos for which the pricelist will apply.
