Currently I am using the WPSC Buy Now Button for the Nextgen Gallery using the Thickbox effect and it's sad to say I am stumped on this one.
When you right click and download you're downloading a blank webpage, which is cool except you can still drag and drop in Safari to the desktop (I heard IE can now do this too) and it defeats the purpose of forcing people to buy the source image/hi res file.
This is a project for a client who benefits from the powerful Nextgen plugin by uploading a hundred or so event photos within minutes and resells them to local publishers - hence WPSC.
The client actually has other plans for the WPSC such as membership subscriptions, future integration with Campaign Monitor etc. but the issue is he didn't want to have to upload each individual image as an individual product + grid view.
What solution/alternative is there? I've tried a few other plugins and these are the best except for this one serious issue.
Other issues are adding to cart etc but I think we can live with the Buy Now button for now.. any ideas?
