When a visitor adds a listing, the first step asks them to upload an image. after the third step, they're again asked for more pictures to be uploaded.

step 1:
step1.PNG

step 4:
s2.PNG

the problem is, the upload from the first step is never successful. No errors or anything, but the image is simply not showin in the listings pictures. The 4th step is working fine. So how can I just remove the add a picture from the first step? I only need the second upload functionality
