My ultimate goal is to do this programmatically, but as a sanity check I'm trying to just post an uploaded photo (from my computer) to a Facebook page using the Facebook Graph API Explorer. I have the access token and photo_upload and publish_stream permissions.
I just don't understand what to do to indicate where the photo is. How can I do it?
Thanks.
I don't think the Graph API explorer tool supports file upload, so you won't be able to use it to check your uploads.
Facebook accepts a url param for image uploads - point that to a full image url, and Facebook should pick it up. Since it's just a string, you can use the Explorer for that.
However, Facebook should come back with reasonable errors for photo uploads - I'd start coding rather than worry about the explorer tool!
Use curl with the -F and "source=" flags and it should work. Here is a code snippet from one of our applications (we construct this curl command from PHP):
curl -F 'access_token=xxxxxx' -F 'source=@/path/to/image.jpg'
-F 'message=' -F 'privacy={"value": "EVERYONE"}'

I managed to post images from Graph API explorer using this!
Hope this helps.
