According to your description, do you have any errors when you switch clicks?
I recommend that you use F12 to see if the console tab has any error message, and if so, I hope you can provide us with a reference.
In addition, the most likely reason is the problem of your image path. Can I see what your FullFilePath stores?
And can you tell us the hierarchical relationship between these pictures and the page you are currently running?
