16969	[UploadImage] Transparency is lost if PNG is copied directly from webpage	Wizard		"== Steps to reproduce ==

1. Use Firefox and go to [https://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png]
2. Right-click the image and select Copy Image.
3. Paste it in CKEditor with Upload Image plugin enabled and configured.

== Expected result ==
PNG image should be displayed with transparent background.

== Actual result ==
PNG image is displayed with black background.
If however I save the image from webpage and copy it within Windows Explorer, it is pasted correctly in CKEditor.

== Other details (browser, OS, CKEditor version, installed plugins) ==
Firefox 32bit v52.0.2, Windows 7 SP1 64bit, CKEditor 4.6.2 Full Package with Iframe Dialog Field and Upload Image plugins

I have attached 2 files. Alpha_yes.png is the image saved from Firefox (it has an alpha value) and alpha_no.png is the image that is copied directly from webpage (no alpha value)."	Bug	new	Normal		General	4.6.2			porjo
