Picture Search Function

i want to know that how to use
Java Script, or CGI, or PHP
to write a function that used to search the filename of a image inside web.

base on the image's filename search

Just like the function that for picture searching in Yahoo.
but just search inside the web!!

Any one can help me??!
i have no idea about that... >~<

What do you mean by inside the web? If you mean within your site, then it is perfectly possible. I would use PHP as it can read directories and find file names. JavaScript would be easier to code but you'd have to manually make a list of all the files that you want it to be able to find.

If yo mean that it should be able to find images on ANY site, then I would still use PHP, although I would not do this at all. I would use images.google.com to get a list of images, then use PHP to format it as I want and output it on my page.

i just search on my own web....
but not outside,
base on filename search..

how to do it?

thanks~
