Photo and Logo issues

[techgasp]

I just tried to add photo and logo in vcard version 3.0 and 4.0 and the images never show in my cell phone qr reader.
I have tested other qr codes with contact photo and my cell phone qr reader display the contact photo.

Was that the reason why you haven't added the photo in your example?

I tested with base64 and without, all tests without success and with different media types formats and small sizes:

photo {
url: 'http://not-encoded.com/my.png',
mediaType: 'png',
base64: false
},
or
photo {
url: 'http://not-encoded.com/mypng',
mediaType: 'png',
},
or
url: 'encoded-link',
mediaType: 'png',
base64: true
},

The QR code gets generated with the photo entry but upon scan it never shows an image... photo and logo. Can you help?
