Some thoughts, in no particular order.

* If you *must* extract the images from the MP3 upon request, make sure you configure a cache policy that optimises the user experience and resource useage.
* How do the MP3s end up on the server? If possible, I'd explore the possibility of extracting the image on upload rather than request, running a tool on existing MP3s to generate legacy images once.
* Another avenue to explore would be having a service that generates a cache of the images, outside the ASP process. This frees you from the constraints of VBScript and COM, although the negatives are a) you'll need to be able to configure services on the server, and b) there's a possibility that an image won't be available for a given MP3 for a brief period after it's been added, before the service re-generates the cache.

HTH, Cheers!
