@nickvelloff The URL is incomplete, can you paste again?

@nickvelloff cannot reproduce that exact error. However I do get a black image output. Looking at the response data from the input URL, it does not set any Content-Header. This combined with no extension means that we don't know which file type is in use.
What needs to be done is to do sniffing on the actual file content header. Which is not something GEGL does at the moment..

[nickvelloff]

So this is a URL that has been consumed by the /share endpoint. Thus any lack of specific image information required is in the flow of the URL data consumption on the API side. Would this be considered a bug I should surface?

Browsers handle this case, so should imgflo. Its just a bit tricky with the
libraries we use.

But probably could write a little image type sniffer and run that on the
files before passing over to GEGL.

Cool well let me know if you would like me to reproduce the specific payload for testing.
