Image download corruption

Sometimes when using downloaders that use the json API images can corrupt. They are incomplete and show part of the image in black.

First I thought this was an issue with the download manager(s). But multiple scripts in python and C# result in the same problem.
 
My theory is that this happens because the processing of an upload is incomplete, but the json data is available before the image itself is, and the script that fetches data from images.json will try to download something that isn’t fully available yet.
 
Is this a known issue and is my theory correct? I hope it can be resolved as it is annoying somtimes.
 
Thanks.

That is possible; you might want to try adding created_at.lt:5 minutes ago as a search parameter to avoid that. I’m not sure what else could be doing that.

That’s clever. I’ll be testing this to see if it helps.
 
If you ever need technical information I could try. But then I would have to spend some time to try and debug it.
