Nopcommerce 2.4
SQL SERVER 2008 R2
I've also tested with upload picture function on this page http://admin-demo.nopcommerce.com/Admin/Product/Edit/96.
When I uploaded a picture and click on "add product picture" button, that picture saved and displayed on grid. But that picture still appeared on upload control, it means if I continue to click on "add product picture" button, the image would displayed on grid as one second, third, so on. I just click on "delete" button at a record (of second, third, v.v. not first), the grid displayed empty. I think the problem has occurred with the images uploaded after the first one.
