Imaging & Servlets

hi all,

i've just written an imaging applet .... and a servlet to handle updates and retrieval of blobs.

The servlets outputs these blobs by one of two methods

1 : I output the image straight to the browser (as content type "image/jpg") so that the

user sees a new HTML page with only the image displayed.

2 : and this is the problem .... when the servlet accepts image(s) .. i create a thumbnail for each.

Now ... how the hell do i dynamically display these thumbnails from a sevlet with HTML .. (remembering that

the thumbnails are also blobs retrieved from the DB) so i cant just link to them.

If i extract the thumbnails to the server file system .. and dynamically create the HTML with the

links .. i have no way of knowing when the user is finished with that page .. and when i can delete the

thumbnails.

Help on this would be gratefully appreciated.

Thanks

Paul Lingwood
