Problems uploading pictures to Facebook wall.
- by Miguel Ángel Ortuño
Hi, i'm trying to upload a JPEG picture to Facebook wall using libcurl. Appareantly the connection is established but cURL hangs when waiting for server response.
The libcurl output is the following:
About to connect() to api.facebook.com port 80 (#0)
Trying 66.220.146.15... * connected
