Hi @rdeh71
I am so sorry you are having problems.
As @Ketch mentions, on the website, if you go to the drop down menu … My listing … Your Home, and scroll down to the photos. on the right hand side, next to each photo, there are little up and down arrows, which will help you rearrange the photos.
You can also use the Cover photo button to change any photo to the cover one.
I hope this helps.
