MATLAB how can I save an image?

Question

I tried the commands:

 imshow(originalImage);
 imsave;

it works, but I want the matlab to automatically save the image in bmp format (in the current folder). I tried to use:

 save('myimage.bmp','originalImage');

the picture was saved, but on the image itself, instead of the picture, I saw this message: "windows photo viewer can't open this picture because the file apears to be damaged, corrupted, or is too large". (the size of the picture is 5kb).

Thanks!

Use the function imwrite to do that:

imwrite(image_matrix, 'myimage.bmp', 'bmp')
