SIDB (Scientific Image Database) is a Web-driven database for (scientific) images. Entry of image meta-data is facilitated through the use of user-definable templates. Users have complete control over who else may see the submitted image and data. SIDB offers various views on the actual image data. Thumbnail plus meta-data can be printed, and multiple thumbnails can be combined in galleries. A freeware version of the Huygens software (http://www.svi.nl) can be used to generate projections from 3-D images (most confocal microscope image formats are supported), as well as MPEG movies, showing the individual layers from the 3-D images.
PhpLabware is a database system with features similar to Filemaker and Access, but is completely Web-based. Relational databases can be defined through the Web interface and extended with PHP plugin code. User and group access is regulated at the record level. It was written by and for life sciences research scientists, but should be generally useful as a Web-based front end to SQL databases.
