@Gozzy82Feb 25.2010 — you cant access any elements on a page from a different domain because of security reasons, if you want to access that page you can use a serverside proxy which loads the external page

@01denauthorFeb 26.2010 — thanks for your reply Gozzy82 i had a feeling about that but was not to sure.

sorry for being stupid but when you say that I can use a proxy what do you mean? ?

I could i guess use php to load it but I don't really know what a proxy is sorry.

@01denauthorFeb 26.2010 — hi again

I have written a curl class for loading the page into a variable and am passing it to a js function see below:

function fillFrame(page){

var ifrm=document.getElementById('myiframe');

var doc = ifrm.document;
if(ifrm.contentDocument){
doc = ifrm.contentDocument; // For NS6
}
else if(ifrm.contentWindow){
doc = ifrm.contentWindow.document; // For IE5.5 and IE6
}
// Put the content in the iframe
doc.open();
doc.writeln(page);
doc.close();
}

'myiframe' is the id of the iframe on my page but when i load the page it does not show in the iframe but outside the frame can you tell what i am doing wrong?

thankws again for your help i appreciate it.

@01denauthorFeb 26.2010 — I have just figured it out thank you it is now loading it iframe but now I guess i will have to set the absolute paths to all images and links using php or can you think of an easier way?

@Gozzy82Feb 26.2010 — hi, glad you got it working, for all the links and images you can use a base tag: http://www.w3schools.com/TAGS/tag_base.asp
