Hi
The app only returns with the original photo.
Given that you can use any 3rd party application to parse that image and
load it's metadata.

This works fantastically well.
I'd like to also show the photo's capture/digitization/whatever-date (or
any other photo metadata) Is there a method to also retrieve the metadata
for the random image or to have this returned in the header/somehow?

I'd just assumed that it wasn't possible to read EXIF data in the browser but as you point out, it seems to be. Thanks! |

There are a lot of JavaScript libraries that can read exif and iptc data.
Here is one that I'm considering using for pigallery:

That's a super nice library. Thanks. It was all going to be easy but then I discovered that nginx's image resizing strips the metadata. Such is software :) |

Im not familiar with that repo, but this file can be updated:
https://github.com/imaginator/smartserver/blob/master/roles/pigallery2/templates/pigallery2.imagilan.conf
The pigallery2 recommend nginx config only allows post/put to pgapi/ path
and it also enables gzip compression (that gives a significant speed up)

Thanks for the update - yes that nginx config was just a hacky way to resize photos before so that the underpowered wall-mounted tablet doesn't choke on large files :) It turns out nginx has a nice way to do this. Or is there a param to pass to |
