Hi guys,
im using Captive Portal page with some info for user. After click to OK they 
are conected to internet.
I would like to add some pictures to C.P. page, pictures are at my web page 
www.page.xy/picturex.jpg

Is it possible? because i have tryed to add source like this:

<body>
<img src="http://www.page.xy/picture.gif" border="0" width="16" height="16" 
alt="xyz">
</body>

This way doesnt work ...there should be allowed some traffic to that page... 
ANY ide?

THX. pet
