 A large JPG uploaded via Media in WPAdmin is processed into various sizes.
 The original renders in Windows 10 Pro Edge/IE/Photos. The processed
 images do not render. Processed images do render in Chrome and Firefox.
 Converting the large JPG to PNG using Photoshop and uploading results in
 processed images that do render in Edge/IE/Photos.

 This independent from Ticket 36534, the Imagick thread issue, which I also
 encountered on my Web hosting virtual private server. The .htaccess thread
 count line fixed my HTTP Error image upload issue. 4.5.2 is slated to
 contain that fix.

 I first noticed this non-rendering issue in 4.5; no change with 4.5.1. I
 was on 4.5 before I ever encountered the image in question.

 This non-rendering image has been discussed with a developer on the Edge
 team. It has been formally submitted to Windows Feedback, too. Is it
 specific to this one file? Is it an Edge/IE issue? I can't tell. Other
 processed JPGs do render in Edge/IE/Photos.

 Original uploaded through Media still renders in Edge:

 Processed 300x228 does not render in Edge:

 Downloading the 300x228 and opening it in Windows Photos does not work,
 either.

 Original file has been attached for reference.

 (The source JPG image is from NOAA, and contains a trademarked image; it
 is used with permission on my site. I do conceded that it may be an image
 conflict, and not necessarily a bug in WordPress. However, it is WordPress
 processing that creates the non-rendering image.)

 With WP 4.5, it was announced that image processing was enhanced, so it
 leads me to believe something with this JPG file is incompatible with the
 changes. I simply cannot determine if it's just this one file, or a
 symptom of a larger problem.

 For comparison, here is an original JPG I created in Photoshop, uploaded
 via Media, which renders in Edge:

 This is the WordPress processed 300x300, which also DOES render in Edge:

 Better safe than sorry to expose a potential bug and have this ticket
 closed, than to let it go unnoticed.
