Dear who-ever reads this,
I created this IGB page that mainly has an image in it wich updates every 5 minutes.
Though, whenever you refresh a page in the IGB it won't correctly update and display the image.
A workaround is to right-click the image, click on reload image, and the reload the page. But that's just plain annoying to do so every time, especially when you log on next day and you still have to manually refresh.
Is there a known fix for this? If not, could this please be fixed in the next IGB update?
Cheers,
- Kw4h

How do you reference the images. The IGB automaticly updates images that are created by php scripts.

the image is drawn, and stored as a .png file on the server.
php script goes like this:
-------
if (image older than 5 minutes)
{
redraw();
}
display();
-------
So it's not a 'direct' output from php, but a real image.

Does the IGB even use the cache header in the http request? What does the server send?

As with all other browsers, write a php script that outputs the image to stdout and reference this script in the <img> tag.

doing so right now:
----------
$im = imagecreatefrompng('./images/map.png');
imagepng($im);
imagedestroy($im);
----------
<img src="./image.php"></img>
----------
Doesn't work like it should either, i still have to 'right click->reload image' before it refreshes

Try sending a Cache: no-cache header with the image.

doesn't work either.
i added a header to the image.php, and a header on the page where the image is displayed.
It's just being ignored.

Not really surprised that the caching headers are ignored by the IGB. Shrug.

This might work or not, but if there is anyway to put a qstring at the end of the image when loading that might trigger the server to re-download it.
so instead of displaying "image.png"
put the date/time at the end of it like "image.png?date=<?php date/time-code?>"
Use seconds so it will be different everytime.

Here is a working example for the IGB: http://bughunters.addix.net/igbtest/imagetest4.html
The php code looks as following:
 Quote:
<?
header ("Content-Type: image/png\nPragma: no-cache");
if (isset($_REQUEST["n"]))
$n=$_REQUEST["n"];
else
$n=50;
$im=imagecreate(250,150);
$darkblue=ImageColorAllocate($im, 0,0,55);
$lightblue=ImageColorAllocate($im, 150,150,255);
$lightblue2=ImageColorAllocate($im, 180,180,255);
$lightblue3=ImageColorAllocate($im, 210,210,255);
$white=ImageColorAllocate($im, 255,255,255);
for ($i=0;$i<$n;$i++)
imageline($im,rand(0,249),rand(0,149),rand(0,249),rand(0,149),$lightblue);
for ($i=0;$i<$n;$i++)
imageline($im,rand(0,249),rand(0,149),rand(0,249),rand(0,149),$lightblue2);
for ($i=0;$i<$n;$i++)
imageline($im,rand(0,249),rand(0,149),rand(0,249),rand(0,149),$lightblue3);
imagepng($im);
?>

EVE doesn't support the HTTP 1.1 "Cache-Control: no-cache" header?

I just tried the thing that Traveler suggested.
It appears that eve does support the "Pragma: no-cache" header, and that works great :)
Thanks for your suggestion though :)
