Have a way to Enable or Disable Downloads for your entire gallery or groups of images, with one setting. Similar to Allowing and Disallowing the Sharing feature. The Manage Deviations would be a logical place for such a batch command.
Most of the people commenting seem to have misread or misunderstood the post. 1. Disabling Download does not disable right-click/save of the picture at displayed size (that would be a much more serious piece of coding), it disables downloading the full file as uploaded (which for photographers is often much larger. 2. This would not in any way allow viewers to download entire galleries with one click- that has nothing to do with it either. It's a function to allow the gallery owner to disable the full-size download option for their old pictures without having to do them all one by one (which really gets tiresome). 3. Nothing can stop a viewer from saving a deviation at the maximum allowed display size. Right-click disable just slows down people who are very very lazy. It just takes 2-3 extra clicks to get around a disabled right-click in Firefox. That's just the risks of the internet.
For the people wondering why someone would want to disable downloads: - Some people don't want their images to be used as stock - Some people have only uploaded low-resolution images, and manips might not look very good on those images
My earlier suggestion that DA disable downloads for the free membership and paid w/o their own displayed art in their gallery should happen in concert with this suggestion. Key here is to stop those who disregard copyright laws or refuse to acknowledge them.
You can post images in your Gallery to be viewed at low resolution, but have a high resolution image for download, if you want to give permission for people to manip the image as stock. There is a new feature that allows you to enable or disable the image download. Since the feature is new, whatever was the default is set for all your images that were uploaded before the new feature was released. For those of us with several thousand images, it would be difficult to go through all or images and enable or disable the download feature. Having a batch command would make it much more feasible.
