"Open in..." for images

I'm using the following code in my Info.plist to get my app to appear in the "Open in.." menu via the sharing button for PDF files:

<key>CFBundleDocumentTypes</key>
<array>
  <dict>
    <key>CFBundleTypeName</key>
    <string>PDF</string>
    <key>LSHandlerRank</key>
    <string>Alternate</string>
    <key>LSItemContentTypes</key>
    <array>
      <string>com.adobe.pdf</string>
    </array>
  </dict>
</array>

This is working fine.

But I cannot get the same effect for any type of image file. I was trying to add this according to some Stackoverflow posts:

<dict>
  <key>CFBundleTypeName</key>
  <string>public.jpeg</string>
  <key>LSHandlerRank</key>
  <string>Alternate</string>
  <key>LSItemContentTypes</key>
  <array>
    <string>public.jpeg</string>
    <string>public.jpg</string>
  </array>
</dict>
<dict>
  <key>CFBundleTypeName</key>
  <string>public.png</string>
  <key>LSHandlerRank</key>
  <string>Alternate</string>
  <key>LSItemContentTypes</key>
  <array>
    <string>public.png</string>
  </array>
</dict>

However, it is not working for images.

Is this supported? Should it work?
