Trying to send a local image via ShareKit to Facebook

I'm trying to modify ShareKit to send an image from my iPhone application to Facebook. I also want to pre-populate the share pop-up window type-in box with some text and send a URL. I created a new method to do all this:

+ (SHKItem *)URL:(NSURL *)url title:(NSString *)title text:(NSString *)text picURL:(NSURL *)picURL
{
    SHKItem *item = [[SHKItem alloc] init];
    item.shareType = SHKShareTypeURL;
    item.URL = url;
    item.title = title;
    item.text = text;
    item.picURL = picURL;
    return [item autorelease];
}

Then within the send method in SHKFacebook I check if picURL exists and send to Facebook:

if (item.picURL) {
  dialog.attachment = [NSString stringWithFormat:
                          @"{\
                          \"name\":\"%@\",\
                          \"href\":\"%@\",\
                          \"media\":[{\"type\":\"image\",\
                          \"src\":\"%@\",\
                          \"href\":\"http://itunes.apple.com/us/app/XXXXXX/\"}]}",
                        item.title == nil ? SHKEncodeURL(item.URL) : SHKEncode(item.title),
                        SHKEncodeURL(item.URL),
                        SHKEncodeURL(item.picURL)
                        ];
        }

Everything is fine. But I already have the images within my iPhone app and would strongly prefer not to have to retrieve them across the internet.

Is there a way to use UIImageJPEGRepresentation to include the image directly into the dialog.attachment above? I can't figure it out. Other answers to similar questions all involve retrieving the URL across the net.

Many thanks!

This is unfortunately impossible with ShareKit (I've used ShareKit myself). At some point, you will have to upload the image somewhere, be it some image server or Facebook--before you can share the image. (Don't forget, sharing the image is a completely different thing then merely uploading to Facebook)

This Facebook document outlines the accepted parameters which are reflected in your question: http://developers.facebook.com/docs/guides/attachments/ As you can see, they always require a URL for the media sharing.

I would recommend that you build out the system for yourself using the Facebook iOS SDK.
