Image preview in Flex

I am working on an image management application. We have an Adobe AIR client talking to a WAMP server. The MySQL DB stores the images as blobs. We have an image search feature. Upon searching, I am displaying the results as XMLList in a popup window and provided a download button. Downloads work fine. I also want to add a preview button to the popup. Please let me know how can I code this. Without having the file on the client, I cannot preview. But when I use save() method, the os dialog opens up. Anything to be done on the PHP side? Please help.

Don't you mean to display an Image? Wouldn't the normal work? Of course, for performance issues, your PHP code must render smaller images (thumbnails).

Correct me if wrongly understood your question. :(
