I use the following code to publish to a users wall in my Facebook app I have just started:
FB.ui(
{
method: 'feed',
name: 'Facebook Dialogs',
link: 'http://developers.facebook.com/docs/reference/dialogs/',
picture: 'http://localhost:8888/project_images/110/110.png',
caption: 'Reference Documentation',
description: 'Dialogs provide a simple, consistent interface for applications to interface with users.',
message: 'Facebook Dialogs are easy!'
},
function(response) {
if (response && response.post_id) {
alert('Post was published.');
} else {
alert('Post was not published.');
}
}
);
Sadly this does not display the image eventhough when I enter: http://localhost:8888/project_images/110/110.png into my browser the image displays without an issue. Also, when I use the default from the example: http://fbrell.com/f8.jpg as the picture: parameter the image shows up fine. Is this not working because of the localhost? I am running localhost off MAMP.
I ran into this issue as well. I think it is because Facebook attempts to fetch the image, and cannot get to localhost.
