Update information as needed

I have a form that uses a booth map in order to pick the spot they would like to set up their vendor booth space.  This map changes throughout the day.  Currently, I am using an image & updating it on my jotform manually. Is there a way for the form to do it on its own, without me having to remove the image & then re-upload the updated one?

I don't think that is possible. You could instead just put an example image of the booths and have a counter that counts the number of booth left available using "Gift Registry" widget

This is just a suggestion though. Not sure if this would work for you.
