Sphinx is a standalone search engine application that can be integrated with your data sources to provide fast, size-efficient and relevant fulltext search functions.

To clear how powerful it is, Sphinx is already used in BlogCatalog, Joomla & phpBB community forums and more.

Sphinx currently supports:

• MySQL
• PostgreSQL
• XML Pipe mechanism that allows indexing of XML data

Some features of Sphinx:

• high indexing speed (up to 10 MB/sec on modern CPUs)
• high search speed (avg query is under 0.1 sec on 2-4 GB text collections)
• high scalability (up to 100 GB of text, upto 100 M documents on a single CPU)
• supports distributed searching (since v.0.9.6)
• supports phrase proximity ranking, providing good relevance
• supports any number of document fields (weights can be changed on the fly)
• supports different search modes ("match all", "match phrase" and "match any" as of v.0.9.5)

XML Flash galleries are very easy to use & update. When there is a flickr support too, than it is great as it will be totally automated.

Polaroid Gallery is a free flash gallery with splash effect that can get the image data from an XML file or a flickr account.

Pictures is automatically scaled, centered and smoothed when they are loaded. Splash loading effect is totally random, this makes the look of the gallery different every time it is loaded. Images can be dragged & dropped anywhere in the gallery.

Besides the image gallery SWF file, FLA source can be downloaded too.
