Question

The images did not load OR missing when I checked it after some days, it was displaying an alternative image instead. Here's my website :

https://klasifikasi-ptpnx-djoembang.herokuapp.com

this is the heroku logs -t (I'm only showing the image request)

it was fine for a day but if I try to access it again on the next day, the images were gone. I can't see any errors. It seems like whenever the status code are 300, it would not displaying I guess?

thank you for your help!

Have you gone through https://help.heroku.com/K1PPS2WM/why-are-my-file-uploads-missing-deleted ?

As per Heroku documentation, the Heroku filesystem is ephemeral - that means that any changes to the filesystem whilst the dyno is running only last until that dyno is shut down or restarted. Each dyno boots with a clean copy of the filesystem from the most recent deploy. This is similar to how many container based systems, such as Docker, operate.
