picture sent in http with base64

Hi,
to provide visual confirmation for
http://beztajemnic.evot.org/index.php?s=1
my server is sending data:image/png;base64 in the http protocoll.
This allows to omit writting picture data on the disk,
actually this part of the disk is read only.

With my KDE/konqueror and Firefox under Linux I can see the
correct picture, but some clients don't see it.
How could I correct this error ?

thank you in advance
Zbyszek

First I would try to make sure the html is correct:-)

<img src="data:image/png;.... name="vconf.png"

is missing: ", after adding it I see "smover" :-)

Well the image is there now, but you still got some errors:-)


If I open Firefoxs Error-Console I can see two messages, complaining
about a unknown property: boder-top
Should be: border-top

I am happy the picture is there.
Do you think it can be seen in all browsers now ?

IE doesn't support data URLs.

It means you don't see the picture, do you ?
What is the correct solution on the read-only server fs then ?

The way i do now is:

function gen_rand_img () {
...
ob_start (NULL, 4096);
imagepng($img);
imagedestroy($img);
return (base64_encode(ob_get_clean()));
}

$head="
<!doctype html public \"-//w3c//dtd html 4.0 transitional//EN\">
<html>
<head>
<title>...</title>
<meta http-equiv=\"Content-Type\" content=\"text/html;
charset=iso-8859-2\"
....";

echo $head;

header("Cache-Control: no-store, no-cache, must-revalidate"); //http/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); // HTTP/1.0

....

echo "
echo "<img src=\"data:image/png;base64,".gen_rand_img()."\"
name=\"vconf.png\">";

sorry,
I corrected this for MSIE allowing to write png image to the filesystem.
To test the original problem now you have to change your brower
identification.

Now I hope everybody can see the picture.
