Gnuplot generated png files not displayed in html files.
Hello kind people.
I'm setting up small asterisk/SS7 server, and writing simple monitoring script.
It basically pulls data from Asterisk to .dat file and then gnuplot is plotting it to .png which itself is displayed in .html file.
Problem is that generated png files are not displayed in any web browser.
At first I thought it was problem with web server (lighttpd in my case, also tried dhttpd), but it displays other image files, pngs, gifs and jpgs.
Am I missing some package? I compared package list to my other servers (they're also running debian lenny), it looks same, and also, this script, works perfectly on ther machines, gnuplot generated png files are perfectly displayed on web page.
