Re: [hobbit] Larrd graphs not working

[Michael Frey <michael_frey (at) glic.com>]

After deleting the lines as suggested, and adding the <89>PNG, the image 
in the viewer is still a black screen.

If I delete the <89>PNG, the file size is zero bytes.

Thanks for your help.

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
