title: Can't open png, saved with Chrome
body: <p>Recently I started studying Android development. To get myself started I'm trying to develop a simple app to track my favorite coffee cups. To this end, I thought I'd download the images <a href="https://www.dropbox.com/s/c4d6ly93j8osvj2/9148239937566.png?dl=0" rel="nofollow noreferrer">(sample)</a> of the cups from the official <a href="https://www.nespresso.com/ch/en/coffee-grid#!/by-range" rel="nofollow noreferrer">website</a>. The good news is that I can right-click and save them as .png files and Android (Studio) can display them. The challenge I have is that I can't open these png's (e.g. to view or edit) in any other program. I've tried Windows Paint, Photo viewer, IE, GIMP... none work. The only program I can view the images with is Chrome. Of course this doesn't help me edit them.</p>
  
  <p>I've searched for answers, but can't find any.
  I've tried renaming to .webp and .jpg, hoping this could do the trick.
  I've tried online file type identifier (checkfiletype.com), which then indicates it's a RIFF file, which doesn't seem very helpful, since it is an image and no audio.
  When I download the images via e.g. Firefox or IE, I get different file formats, which seem to be significantly larger file size, so I'd prefer to use the Chrome downloads.</p>
  
  <p>I'm out of options. Would anyone know how to get these files opened/edited?
  Preferably I'd be able to open with GIMP. At the moment however I'd even be happy to simply settle to be able to view them outside of Chrome.</p>
