Didn't your users ever complained about the picture uploading, that it is so annoying to upload and delete one by one picture ?
Not to mention they have to keep scrolling down whole page to upload another one?
What if user once uploaded all pictures wants to change the first picture to another one? YES you thinking right he has TO DELETE ALL ALREADY UPLOADED PICTURE and start over again. This torture for your sellers and risky for you that seller will loose patience and goes elswhere to list his items what means loss for you.
This mod will change the way your users uploads the pictures and videos and they will love it. Now they will have seperate step for their media to manage and everything on the fly , no more refreshing the page, No MORE SCROLLING DOWN, no more deleting all pictures to change the very first one.
Everybody knows that "pictures" sells. So make your users life easier, Give them the right tools to do the right sells.
