View multiple images in a page
Hi,
I'm able to run the following code in the jsp. But my
problem is I have multiple images in a table and would
like all of it to be display as an icon. I have tried
to put while(rs.next())... it doesn't work.
How should I go about to do it.
Thanks.
Tan

Hi Paul I went to the site and I can't look for the page. If you dont' mind to get the the exact url.

Once you pull your image data from MySQL (I assume you're using some kind of script for this), then you do this the same way you'd do it if MySQL weren't involved. Send your HTTP headers to indicate the MIME type and the length, a blank line, and the image data. If you want some example code in Perl, get the webdb distribution at http://www.kitebird.com/mysql-perl/ and look in the distribution's image directory. sql, query __ Do you Yahoo!? Yahoo!

Re: View image from browser
Hi, Sorry I didn't check in the pdf. Thanks guys. By the way, I found there is an article from www.onlamp.com/lpt/a/a370 it uses the php to do the same thing. Thanks once again.
