Hi,

I spent quite a while to code the preloader scene to download few images from photobucket, so that i can update photos, instead of compiling the FLA everytime.

The problem is, everything works accordingly in FlashPro by using "Test Movie", however after I publish it as SWF,the SWF will play in IE8/Chrome, but it won't connect to photobucket to download the images, thus, the preloader scene never get pass.

Any suggestions?

SecurityError: Error #2122: Security sandbox violation: LoaderInfo.content: http://www.autohotkey.net/~evanlim86/EL2_29f.swf cannot access http://img.photobucket.com/albums/v439/evanxxxm/elsesite_flash/th_1.jpg. A policy file is required, but the checkPolicyFile flag was not set when this media was loaded.

    at flash.display::LoaderInfo/get content()

    at EL2_29f_fla::MainTimeline/loaded()

a policy file is not needed to download cross-domain images.  however, because you're trying to access your loader's content, you're triggering a need for a cross-domain policy file.

to remedy, either upload a cross-domain policy file or push your loaders into that array and not that content property.

Thank you kglad, I was not aware with the cross-domain policy. My earlier version was using actionscript 2 and everything is compiled within the SWF. I am reading through the documentation, and it seems I need to change the XML file on the uploaded website?

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="http://img.photobucket.com/albums/v439/evanxxxm/elsesite_flash/" />
</cross-domain-policy>

I uploaded the above lines within crossdomain.xml and put in my autohotkey.net server (same folder as the EL2_29f.swf,AC_RunActiveContent.js)

http://www.autohotkey.net/~evanlim86/crossdomain.xml

Still the same, is there something I am missing here?

yes, you're missing something.

but, why bother with a policy file when you're not using anything that requires a policy file.  just push your loader into that array instead of a content property.
