Ich habe ,mit helfe von PHP, ein abbildung gemacht durch von Kommandos wie 'imageline' Gebrauch zu machren. Am ende von meinem Programm habe ich die unterstehende Kommando's geschieben um meine Abbildung zum browser zu laden. Aber statt eine Abbildung sehe ich fremde Zeigen und Letters an meine Bildscherm. Wie ist das Moglich? Ist es moglich dass meine browser kein 'header'-Kommando unterstutzt?
Gruse, Martijn Kamps

Im working with frames. The frame contains two parts. When the cursor is moved over the higher part of the frame, a picture is created and continuesly recreated in the lower part of the screen. Every time the cursor is moved in the in the higher part the picture in the lower part is recreated in a littlebit different way depending on the position of the cursor in the higher part. In the higherpart of the frame a timeline is visible including with a magnifying glass which can be moved move. In the lower part a magnified, short part of the timeline should be visible.
The code for the higher part of the frame is :
(The name of the file is:'makeTimeLine')

One hint:
If you want make pictures with the image functions, the only output in this file that is allowed, is eg.
header(...);
imagepng(...);
exit;
No echo, no html, no blank, no CR before and after this commands.
This Script acts like a single picture.

What does 'CR' mean?
CR = carriage return
Are the variable assignment commands also not allowed?
PHP-Code is allowed. But no other output to the browser, than the output from header() and imagepng().
