Thumbnails
I've literally just finished implementing thumbnail support in ByteHoard/e. Unlike previous versions, they're not generated on the fly, but rather whenever the file changes - the same goes for all the file metadata ByteHoard uses, like mimetypes (which now work, too) and file sizes.
As a supplement to the thumbnails, two other features have appeared. Firstly, files now have relevant icons and type descriptions, and secondly, the administrator interface has a button to entirely rescan all the files a user owns, for those cases where you've managed to confuse ByteHoard.
I've also closed a few bugs, including quota usage not changing when you delete directories, and not being able to remove administrator abilities from users.

You are da man :) Checking the new one out now!
Hmm, the svn version isn't yet reflected to add the new 'md5' field in the table, so be careful.
'md5', varchar(255), in files, btw.
All fixed, excellent!
you´re great man - impressive work
i really looking forward to the new bytehoard version
//hups
when is the new version coming out? :D
Hmm, sometime. I can't be more specific - my free time is pretty unpredictable, and I have a few other things competing for attention. Nevertheless, it should be soonish - less than a month, at least.
Is the latest stuff always checked in svn?
i would like to check it out and contribute to it...
Not always; I try to only commit when everything at least has a chance of working, and currently the code is in a very unworking state. I'll try to put some time in over the week and commit my latest round of changes; you can always check it out now, though, since most of the code is unchanged.
