Any idea whats wrong with this code?

I just replied in your other cross post

Please help me with the code below

IMHO starting with a simple script at first is a good idea. That’s how I prefer to work up a script. Working - tweak until it breaks - fix - rinse, repeat. Notice the getImageSourceByDate() and the return lines. The getImageSourceByDate() line is “calling” a function named “getImageSourceByDate”, but your code (as it is) has no such function. If you open your browsers dev tools console you may see an “undefined” error message that could help point you to the problem. Sometimes functions only…

Nothing personal, but I for one have a difficult time keeping up with cross posts. Please stop doing it.
