Using my Phone for image processing

Hello everyone, I'm trying to get images from my cell phone camera. I have downlaoded an app and can use it on my browser but on MATLAB I'm having this error, any help will be appreciated.

Error using imread (line 350) Can't read URL "http://MY_IP/shot.jpg".

Error in imagedeneme (line 4) ss=imread(url)

BTW this is the code I'm using:

url = 'http://<ip address>/shot.jpg'

ss = imread(url)

fh = image(ss)

while(1)

    ss  = imread(url)

    set(fh,'CData',ss)

    drawnow;
end
