Is there a picture ??

Hi all,
just installed qcam 0.3

It seems to work, the output generates a file of about 20kb

Is this correct.

i give this command

qcam | cjpeg -grayscale > test.jpg

according to my knowledge this should give a JPG image called test, right ??

when i look at the picture, it's almost blank..

Is there a way to see if the qcam actually gives a picture, i.e. how can i
look at the pgm output ??

Thanks, Paul
