When we released drag and drop image upload, we saw a huge uptick in the number of front images Zistlers put into the system. Dragging and dropping was just easier then using the flagging form. However, as had been pointed out by many, there was no way to upload back images via drag and drop so our back image count did not see the same boost. Today that changes with the deployment of drag and drop upload for back images!
We have added the ability to “flip” cards in the gallery view when editing your collection by using the link in the screenshot below:
Clicking this button flips over all of the cards in the gallery view and shows you their back images.
When the cards are showing their backs, you can drag and drop back images onto them just as you would the fronts. So if you want to upload back images, just flip the gallery view and start dragging and dropping.
