           Summary: Thumbnails in HTML interface for CD/ DVD archives
           Product: digikam
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Export
        AssignedTo: digikam-devel kde org
        ReportedBy: msp debian org


Version:            (using KDE KDE 3.5.5)
Installed from:    Debian testing/unstable Packages

Issues:

1. When archiving an image collection with HTML to CD/DVD generating the thumbnails can take a very long time for to process the large number of files involved. Especially if you have just uploaded photo's from a friend's camera and you want to save their photo's quickly to CD so they can take away (and the HTML interface would be nice)

2. When making an CD archive, one generally only wants one copy of the images, rather than the image and thumbnail, making two copies of the image on the archive media. Again for said friend to take away a copy of their photo's on 'storage' media.

Proposal:

When generating the HTML interface for a CD with 'thumbnails' it is possible for for the HTML interface to reference the original image and use the IMG HEIGHT and WIDTH tags to provide the scaling for 'thumbnails'.

Pre-scaled, processor intensive at creation time, thumbnails are good for a web based HTML interface over low bandwidth Internet

A CD based HTML interface generally has high bandwidth (disk access) to the full size image to download the image and allow the browser to do the scaling via the HEIGHT and WIDTH tags. Thus the need for pre-scaling is not as necessary.

Benefits:
1. The creation CD with HTML interface can occur in realtime as there is no resizing for thumbs. Just writing the raw images and some HTML wrappers.

2. The CD archive only has one copy of each photo. So end recipients aren't confused as to why there are two copies of each image, and don't use the thumbnail thinking it is the full version.
