error

 A common reason uploading of images fails is because the server runs out
 of resources while creating image sub-sizes. That results in either a
 timeout or out of memory errors.

 In these cases the image file has been uploaded successfully but some or
 all of the sub-sizes haven't been created. Because of the PHP fatal error,
 the response to the browser/client is an "Internal Server Error" (HTTP
 500) which currently results in showing an unfriendly/non-actionable "HTTP
 Error" message in the UI. It also leaves the "orphaned" image sub-sizes
 that were created before the server crash in the upload directory.

 After #40439 and [45538] it became possible to create the missing image
 sub-sizes when an image file was uploaded successfully. Ideally that
 should happen right after the file was uploaded, so the user has access to
 all expected sub-sizes.
