Hi
I am facing th same problem here http://www.pocketmac.net/coverflow/main.html where images are loaded from http://www.pocketmac.com.
I have gone through the post and also attempt the proxy method given on this url http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_16520&sliceId=1
but it has of no use as of now. Also please note that i done have crossdomain file uploaded as yet.
Please suggest the appropriate solution so that i can close this issue.
Thanks

The only problem I have with using a proxy is that it starts stacking up the requests to the server. In a small application this isn’t really an issue, but lately all of the projects I’ve been working on are large scale applications that are used by millions of people. So, avoiding unnecessary requests becomes very important.
Luckily, we’re getting around it by moving to AS3/Flex which provides a much easier way of dealing with the problem.

Paul normally when there is some asset loading from other domain the flash player would check for the crossdomain policy file at the default location (root). We should use that only when we are loading the file other than the root location…

I think the best method to this solution is to by pass that using the proxies and shims… I think this would be allow u to do that…. But I dont know whether i were 100 percent true about it….

Thanks Paul, I would try it. But doesn’t Flash Player automatically checks for crossdomain.xml in default (root) location…
I have deployed it on asset server. BTW! I am using Adobe Flash Player 8, I would try…
Thanks again..

You may need to use .loadPolicy() before you draw the bitmapdata, so Flash knows it’s allowed to access the data before it does.
Here’s the official line: http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_16520
(personally I think this whole crossdomain/bitmapdata restriction thing is utterly retarded, but there you go!)
