Extension icons are missing once it is being uploaded to Chrome Web Store

问题

I'm trying to upload my first Google Chrome extension, but I have a strange issue.

My manifest file is as follows:

{
  "manifest_version": 2,

  "name": "Chat About",
  "description": "Chat about the content of the web page you're currently visiting with other visitors.",
  "version": "0.0.1.1",

  "icons":
  {
    "16": "icon16.png",
    "32": "icon16.png",
    "48": "icon48.png",
    "128": "icon128.png"
  },

  "browser_action":
  {
    "default_icon": "icon.png",
    "default_popup": "popup.html"
  },
  "permissions":
  [
    "activeTab"
  ]
}

The content of the source directory is as follows:

icon.png
icon128.png
icon16.png
icon32.png
icon48.png
manifest.json
popup.html
popup.js

The unpacked extension icons appear, as shown here:

But as I'm trying to upload it to Chrome Web Store, the icons are missing, as shown here:

I couldn't find any solution to this issue. I have no idea what's wrong here.

回答1:

This icon uploaded separately in the Developer Dashboard.

Be noticed that this icon should be drawn with following rules (see Supplying Images):

The actual icon size should be 96x96 (for square icons); an additional 16 pixels per side should be transparent padding, adding up to 128x128 total image size.
