Add image previewing

[rhld16]

This feature displays a modal for any image as a preview so you can view the image without downloading it. All other files download as usual.

Thanks very much! It's already merged locally. Will be published with a few other updates within the next days :)

[PhiTux]

So your code is successfully merged and I did add/fix two other things. On local development everything is working fine for me. But not within a docker-image. So it will take a few more days probably to fix the problem with docker...

[rhld16]

Those changes look great! I noticed two things with the Docker build, my current implementation makes passing the PORT variable mandatory as well as an issue with /api calls being redirected to 'localhost:5000'.

[PhiTux]

Yes, I did also notice this thing with 'localhost:5000'...

The problems seem to go back until commit 911e134. When I rebuild this commit without using cache (!! -> docker build --no-cache ...) then I get the same errors. So perpaps all the new multistage-builds where just working because we both were building the recent docker-images with using cache!? Just an idea...

[rhld16]

That would make sense since I'm certain that it's a misconfig with the nginx config files. At least we caught this now rather than later at least xp

[PhiTux]

No, I think it's not nginx, but gunicorn is not running inside the new multistage docker!

[rhld16]

Oh, that's unexpected... I'll try take a further look into it later

[PhiTux]

:D Same here

[PhiTux]

Okay, perhaps I found the mistake... If that's true, than it was a stupid mistake by me... Let's see

[PhiTux]

Was a missing requirement/dependency for python - my bad Now, everything should be fine :)

[rhld16]

Ah, nice catch! Can confirm the image works on my instance
