[flask] show external images with an app. running on localhost
Problem
I have a Flask app. that I run on my local machine. I wrote it years ago and it worked well at that time. Now, I tried to run it again but the external images didn’t appear, they were broken. These are images that are located somewhere else, I just link them. When I copied their URL and pasted in the location bar of the browser, they appeared. What da?
Solution
It seems Firefox is blocking localhost, so when I visited http://127.0.0.1:5000, some of its elements got blocked.
As a workaround, I added the following line in my /etc/hosts file:
127.0.0.1 jabba-hq
Then, when I visted http://jabba-hq:5000, the images appeared normally.
