Pictures not showing in Store Manager

I have tried searching for an answer to this and couldn't find one.  Perhaps someone knows the answer to this.  I am trying to take off an out of stock picture because I have made more of the product.   When I edit the listing in store manager, no pictures show up.  I don't even have the option to re-upload the pictures to the listing.  It says "Pictures:"  and then nothing.  No boxes to put your pictures in even though I originally had 3 pictures there.  This has happened to me before with this same product and eventually I just had to relist it.  Why is this happening?  It is really annoying and time consuming to have to keep relisting it.

 

Thanks,

Jessica
