flex - check image dimensions before upload using filereference

Question

Hi

In my Flex application, I use a FileReferenceList that the user can populate with multiple files using fileList.browse() before upload.

I check each file's size and use fileList[i].upload() to upload to my server, this works fine.

I have a suspicion that this is not possible, but before upload I would like to convert each FileReference into an Image in order to check it lies within certain dimension tolerances.

I realise I can do this server side, but ideally I would like the check to appear on both client and server. Can anyone offer any help?

Thanks!

Take a look at this post at the Yahoo! Flash Blog. Flash 10 lets you work with images locally. They give a nice example with code of how you can process FileReference objects, specifically image files.
