If you put http://ichart.yahoo.com/t?s=MSFT in the broswer, you get an
image with MSFT chart. Could anyone tell me what technology is used to
generate this pic?

Thanks,

1) Server side script is called by the URL
2) Script looks up the data from database or something
3) Script constructs a block of image data based on the results from the
database
4) Script sends back appropriate MIME-type headers (image/png, for
instance, which this is) and the data block after it
5) Browser knows no better than that it receives an image and displays
it.
