Sharing facebook photo (really a facebook photo) using mobile web app & Feed Dialog.

The problem: Cannot send facebook's photo to the Feed Dialog.

All code works great. I get all properties as they sent to the function. 

    FB.ui
        method: "feed"
        link: 'url'
        app_id: myAppID
        name: 'photo's name'
        description: ''
        caption: $('#albumName').text()
        picture: 'http://myUrl.com/logo.png'

    , (response) ->
        if response and response.post_id
            console.log 'Photo was shared'
        else
            console.log 'Photo was not shared. Please try again'

If I place a static photo, to represent the Picture parameter, all goes fine, But if I try to call a facebook picture I try to share, then I get a 500 server error.

GET https://www.facebook.com/dialog/feed?access_token=...662390597_s.jpg&sdk=joey 500 (OK)

This is totally bizarre. The URL that goes to the dialog iframe, goes with all the needed parameters, including access_token.

It seems like a design issue. Like someone in facebook don't want us to pretend to be facebook when we customly share things using their feed dialog, when we share facebook photos.

Am I right?

!!! Problem Solved !!!

Facebook don't accept their own CDN as a source. We need to bypass that in order to share, therefore we can reshare a facebook the photo using a proxy.

http://images.weserv.nl does the job. Facebook accept the image as a picture param, and this way you are able to reshare their posts.

Usage example (plus width and hight to improve performance)

'https://images.weserv.nl/?url=' + facebookImageUrl + '&h=200&w=200'

  • Can you create a jsfiddle demo for that? if the FB Url working under your login context, therefore it suppose to work. – neoswf Apr 07 '14 at 00:45
