After running the commands as you outlined below, the output in file.png is: Content-type: image/png Expires: Thu, 29 Dec 2005 19:26:06 GMT

If I view the file.png file with a png viewer, it is only a black screen.

You must delete the "Content-type: image/png", the "Expires:..." line, and the blank line. Those lines are headers for the web browser, because the output is supposed to be a web response, and not simply a PNG file.

For the file to be a valid PNG file, it must begin with

<89>PNG
