wifi shield and thingspeak

I made a ThingSpeak account in order to try to get the Arduino to interact with Twitter though ThinkSpeak. First, I messed around with ThinkSpeak a bit by setting up TimeControl with my Twitter account to see if I could set up a certain time a customized tweet could be sent to my Twitter account through ThingSpeak. It worked, so then I continued with connecting my Twitter account with ThingTweet. Right now, I am thinking about setting up a senor on the Arduino and having ThingSpeak send a customized tweet either my personal or a new Twitter account whenever the sensor is pressed. I would like to attach the senor to the shutter button of a camera and have the senor send a tweet saying "A picture has just been taken!" or something like that to a Twitter account. I think it would be interesting have the Arduino connect to a camera because I could then connect the metadata of the photo and the information from Twitter together in order to figure out what picture was taken at what exact moment.

I successfully got the wifi shield to connect to my computer, but was not successful with trying to connect the senor with code to ThingSpeak in order to send a tweet to my Twitter account.
