Hi, I have checked out the HTML 5 specifications for geo-location api, file uploading api and canvas container.
At present, all the attachments are stored in database irrespective of their nature (the old photo album also uses db to store images). I browsed to find out which is better for storing image files - database or file system and found that most of the posts favored filesystem (in case of large number of images). I need your suggestion regarding which one is better in xwiki's context. In case of using filesystem for storing image files, migration of older version photo albums will be complicated as image files will need to be imported from database to file system. Secondly, most of the online photo album application (flickr, picasa web album, facebook) uses image compression for rendering images fastly on slower networks, so do we also intend to use some compression algorithm and optimize the image files for display on web. (xwiki can have something of this sort that is if image size is more than some threshold value (say 1 Mb or 512 kb) then it can be stored as a compressed image). I haven't checked out which algorithms are used and does there exist any library or API for image compression, so can't say how much time it will take to implement. what about sharing photo album only with a specific group not all users and also having manipulating rights to some users only (unlike the old photo album application, any registered user can add or delete photos created by some other user)?
