Remove Watermark After Customer Pays Access Fee

Is there a way to remove the watermark from the images once customer pays access fee to the gallery ?

We want customers to see the watermarked photos, and once they do and like them, they can pay access fee, and watermark is removed and download option is added, and they can download the files.

I found paid access feature, but that doesn't remove the watermark issue we have right now. We send galleries to customers, and when they pay the invoice we have to manually replace the images with non watermarked ones, and add download feature, and that is a bit problematic and takes extra time.

Thanks.

Downloads from orders won't contain a watermark unless you set the download product to watermark them.

So they can be watermarked in the gallery, but when they purchase and download, the downloads won't have a watermark on them.

Thanks Tim for your reply.

I am aware how paid download works. But we want to achieve something different than simple download purchase. We want to send a link to a gallery that will have paid access request. Once customer is happy with the images, they can pay the access fee and automatically remove the watermark from the images, and get access to all image download. I hope I am making my self more clear now.

Sorry, there is not an option to do that.

There are also Buy Alls where they can buy all photos then download without watermarks. 

Thanks Tim. I suspected that.

I am aware of the Buy Alls option, but it is not what I am looking for, as it will only allow to download the uploaded to the gallery downsized versions of our files, but watermarks will stay on the gallery images. Also we provide full size files as a Dropbox link in our galleries instead of actual files, because we can't upload >48Mpix images to our galleries, as that would kill our Sytist server (I actually tried that).
