Description Alex Hermann 2004-11-18 20:42:50 UTC

Version:           0.7 (using KDE 3.3.1,  (3.1))
Compiler:          gcc version 3.3.5 (Debian 1:3.3.5-2)
OS:                Linux (i686) release 2.6.9

The current way thumbnails are created make them quite unmanageble.
1) The original filename can't be deduced from the filenames in ~/.thumbnails. Thus one can't decide which thumbnails are old/unused and may be deleted.
2) Other users/programs sharing the album dir need to duplicate the thumbs as the original thumbs' are inaccesible to others than the user that created them.

So,
my request is an _option_ to save the thumbnails in the album folder. Preferably in a .<size> folder (ie. .100 for 100x100 thumbs, .160 for 160x160 thumbs, etc). This makes the thumbnails more usable for applications other than digikam. (For example, another user or a php web gallery using the same album folder and without access to the user's home dir). This will avoid duplicate thumbs to be made several times.

Alex.

digiKam uses freedeskop.org thumbnail specifications: 
http://triq.net/~jens/thumbnail-spec/index.html

all standard compliant software on unix (including konqueror, gwenview, showimg, ..., nautilus, gthumb, ....) use this repository of thumbnails.

Ok, I've read up on that: that same standard also provides for 'Local Thumbnail repositories':
http://triq.net/~jens/thumbnail-spec/local.html

I think my request could be fitted within that definition, but let me rephrase it a little:

I request an option so that an album (and subalbums) or entire gallery uses a 'Local Thumbnail repository' as specified by the aforementioned freedesktop.org thumbnail specifications.

I hope you will take this into consideration.

read the text at the link you posted again carefully. to quote from the text:

" A local thumbnail repository should be considered read-only. A program should never add or update a thumbnail in the local thumbnail repository. Such a repository should only be created on special request by the user. If a thumbnail is outdated or corrupt, a program should create a new thumbnail in the global thumbnail repository, and not update the local thumbnail repository."

this local thumbnail repository specification is meant for folders which will eventually be turned into a read-only one, for eg, CD archiving.
