Just wondering how Google Image Search Engines do it?
 

how does Google Indexing Engine create thumbnails of images around the web?

I guess it will first download the image into the server and then resizes it and then stores in the server....

Does it use some kind of Java applet to create the thumbnails? Or J2EE does it for them?

And what about other image search engines?

thanks, world-class experts @ L-Questions!

You might want to look into Imagemagick or GD for creating thumbnails.

I agree with the previous poster. ImageMagick or GD make more sense for large amounts of thumbnails, due to their lower footprint when using system resources. JAVA and applets are quite overkill for such tasks. Google has a stored version of every page and image that they have indexed, so they certainly store an extremely large amount of data day by day.
