Could you help me test this seemingly valid image with geturl.php?

are you using the docker container or did you install it yourself?

If it's the latter it looks like you're missing some libraries.. does the server have the file command?

Its using shtripok's docker (necessary for arm compatibility too I think). My docker-compose.yml section:

  pictshare:
    image: shtripok/pictshare:latest
    ports:
      - "127.0.0.1:8537:80"
    volumes:
      - pictshare:/usr/share/nginx/html/data
    restart: always

Did you test this one out?

edit: I also forgot to mention, that most urls work, its just some don't.

Actually the latest official docker images detect the architecture and should work on ARM without a problem

But it seems that the site you're using is checking some sessions or something because when I open your image in the browser it works

But when I download it with curl

curl "https://i.guim.co.uk/img/media/4d908693e566fdd7f8cdeac559f6375b739887a3/356_37_3264_1958/master/3264.jpg?width=1200&height=630&quality=85&auto=format&fit=crop&overlay-align=bottom%2Cleft&overlay-width=100p&overlay-base64=L2ltZy9zdGF0aWMvb3ZlcmxheXMvdGctZGVmYXVsdC5wbmc&enable=upscale&s=3a70177dcc60673c606302d96fcbd9bc"

It's answering with

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

</html>

So it's not a problem with Pictshare, it's the caching server that required some headers probably

Hrm this is strange... when I run that exact same curl command on my local machine, it does download the picture fine. What curl you on?

Sorry I copied the link after I put it in my browser.

when you curl with the original link you posted

curl "https://i.guim.co.uk/img/media/4d908693e566fdd7f8cdeac559f6375b739887a3/356_37_3264_1958/master/3264.jpg\?width\=1200\&height\=630\&quality\=85\&auto\=format\&fit\=crop\&overlay-align\=bottom%2Cleft\&overlay-width\=100p\&overlay-base64\=L2ltZy9zdGF0aWMvb3ZlcmxheXMvdGctZGVmYXVsdC5wbmc\&enable\=upscale\&s\=3a70177dcc60673c606302d96fcbd9bc"

You'll get the error. It seems one of the variables attached to the image is a session ID that's not available for long

That one is different than the link I posted at the top, it seems to have a lot of extra slashes.

This command is correctly downloading the image: curl "https://i.guim.co.uk/img/media/4d908693e566fdd7f8cdeac559f6375b739887a3/356_37_3264_1958/master/3264.jpg?width=1200&height=630&quality=85&auto=format&fit=crop&overlay-align=bottom%2Cleft&overlay-width=100p&overlay-base64=L2ltZy9zdGF0aWMvb3ZlcmxheXMvdGctZGVmYXVsdC5wbmc&enable=upscale&s=3a70177dcc60673c606302d96fcbd9bc" -o test_img

Did you rawurlencode the URL before attaching it to https://MY_PICTSHARE.com/pictshare/api/geturl.php?url= ? because that url has "&" and "?" in it so if you use

https://MY_PICTSHARE.com/pictshare/api/geturl.php?url=https://i.guim.co.uk/img/media/4d908693e566fdd7f8cdeac559f6375b739887a3/356_37_3264_1958/master/3264.jpg?width=1200&height=630&quality=85&auto=format&fit=crop&overlay-align=bottom%2Cleft&overlay-width=100p&overlay-base64=L2ltZy9zdGF0aWMvb3ZlcmxheXMvdGctZGVmYXVsdC5wbmc&enable=upscale&s=3a70177dcc60673c606302d96fcbd9bc

Pictshare would only see url=https://i.guim.co.uk/img/media/4d908693e566fdd7f8cdeac559f6375b739887a3/356_37_3264_1958/master/3264.jpg which will return an invalid image.

if you rawurlencode it to https%3A%2F%2Fi.guim.co.uk%2Fimg%2Fmedia%2F4d908693e566fdd7f8cdeac559f6375b739887a3%2F356_37_3264_1958%2Fmaster%2F3264.jpg%3Fwidth%3D1200%26height%3D630%26quality%3D85%26auto%3Dformat%26fit%3Dcrop%26overlay-align%3Dbottom%252Cleft%26overlay-width%3D100p%26overlay-base64%3DL2ltZy9zdGF0aWMvb3ZlcmxheXMvdGctZGVmYXVsdC5wbmc%26enable%3Dupscale%26s%3D3a70177dcc60673c606302d96fcbd9bc

and attach it encoded to the api, it works on my end
