You have to use a new name for each image; e.g., for your i'th image:

filename = sprintf('myimage%02d.png', i);

I want to use for loop but I don't know how because I want to save images from webcam 10 times.

[Thorsten]

 for i = 1:10

   I = ... % get image I from webcam
   filename = sprintf('myimage%02d.png', i);
   imwrite(filename, I)

 end
