Newly transferred files (images) only showing when site is browsed on local device

Hello,

I am really stressing trying to figure this one out so any help is greatly appreciated. The site I am working on is www.jessicalwhor.com and it is in its infancy stages, so please don't expect a fully-realized site. However, I'm having trouble moving past this initial issue. For some time, I was able to put changes on the domain rather easily, however now I am not able to. I recently updated the background image, but the changes are only displaying on my device (the local device) and not on my cell browser or on my partners laptop on any browser. I have tried all browsers, and have cleared the cache seemingly hundreds of times now. I even went so far as to download FireFox on a device that has never had FireFox installed. The new file that is to be displayed has a filename of "JessicaNew1.png" and the one that consistently displays no matter how frequently I remove it from the /public_html/ file is named "JessicaBackground.png." I've double checked that Dreamweaver is putting the files on the correct server. The domain is hosted on Bluehost. I am using Dreamweaver 19.2.1.11281. I am using bootsrap. On my screen, when the remote server is selected, the only image that displays in the "images" folder is the new one - I have no idea why the old image would still be displaying on all devices except for my own. I suspect some of my code may point to a local file, but I have combed through it and can find nothing. I'm reall desperate here, so thank you for any additional info you can provide me with. I am attaching some screenshot of what I believe to be relevant information. Thanks again.
