I am working on a site that sells canvas prints from a variety of different photographers, I want to have a low res small sized photo unwatermarked in the featured collections section but when you click on it I want to have a higher res watermarked version. Currently there is only the same photo been reduced by shopify but still with the watermark I hope this make sense.
Are you using one of the Shopify's free themes? Are you expecting this functionality to be leveraged by the theme, or you have an app that is doing that?
Would be nice to have some more context to be able to help.
