why not store the assets in a database, and write the image direct as raw?

Subject: dynamic image assets?
Hi,
I'm sure there's a simple solution to this problem, but I've yet to figure
out just what it is!
I have an image associated with each subscriber that registers with my
application, and on login I'd like to show them their picture along with
their subscriber details.
I know I can add an asset to the .page and have the Image component pick
this up and display it
<asset name="subscriber" path="/tmp/subscriber.gif" />
<component id="subscriberImage" type="Image">
<binding name="image" value="getAsset('subscriber')">
</component>
The problem with this is that if I have 1000 subscribers, I need 1000 assets
in my .page. I would like to store the image location as a property of my
subscriber data object and retrieve the asset like this:
<component id="subscriberImage" type="Image">
<binding name="image" value="getAsset('ognl:subscriber.pathToImage
')">
</component>
Unfortunately, tapestry won't evaluate the ognl expression in the getAsset
method call, and I get an error "value for parameter image in component is
null and a non-null value is required". If someone has a solution to this,
I'd be interested the hear about it.
Regards, Brian.
