Website with auto updating image from latest file in folder

I am a noob with everything related to coding, except for some knowledge of the linux command line. Anyway, I have this idea for a project. I need a website with an image that updates every few hours or so. I have a folder in google drive, and every few hours a new image is uploaded. These times are not regular, but as long as the website gets the new photo within an hour-2hours, it will be fine. I was thinking of making an alias folder that links to the latest image in a folder (like how apple does it with time machine backups) if that makes sense. Then I would copy the link on google drive (of the alias folder) and put that into wordpress. It would pull that link, which would go to the latest image in a folder. I have a feeling that this would not work out, however. Basically, I just want an automated updater to pull the latest image from a google drive folder and publish it to the website. If it needs to be local, I could use the backup and sync for drive and the google drive folder would be synced to my local machine.

Another thing I was thinking of was a automatic slideshow maker. I would use some kind of script in google to delete all files in a folder except for the latest one. Then I would use the automatic slideshow maker to make a slideshow based on data in the particular google drive folder, which would be the latest photo.

Again, these are just some ideas that I have had, and they are both likely not going to work.

I have a self hosted web server (docker) and could put a wordpress instance on that, or I could use an online website builder like weebly or wix or even google sites. It needs to be free because this is for a community service project and I do not want to have to constantly fundraise. However, if my only option requires payment, I am open to that.

Does anybody have a solution for this?

Thanks!
