Hi Nathan,
Thanks a lot for the suggestion. It is working fine for an example code
I have used to test it. The code I have written after your suggestion is
as follows.
<?php
$location="C:\wamp\bin\apache\apache2.2.8\htdocs\Bldgs_lots\SQUIRES.jpg";
header('Content-Type: image/jpeg');
imagejpeg(imagecreatefromjpeg($location));
?>
The above code is yielding me a picture. Now, When I tried to use it in
my original code it is not giving me the image. Instead it is giving me
this warning *Warning*: Cannot modify header information - headers
already sent by (output started at C:\wamp\www\mysqli.php:65) in
*C:\wamp\www\mysqli.php* on line *221*
and a lot binary characters again instead of the image. I know something
about this warning that we should not output anything to the browser
before the header. But I cannot do that, since I need the user input
using a html form and I use the input to fetch the data and dispaly it
in a table along with the image. I am posting the whole code below.
Please do let me know about any changes, corrections or modifications
that are needed. The image display code is towards the last.
Thanks,
Sashi

The thing is, I do not have a website or a place where I am storing my
images. I am storing the images on my local PC in folder as mentioned in my
earlier post. I have tried using only the

imagejpeg($img);
imagedestroy($img);
}
Which you have suggested. This is the piece of code which is returning all
the binary character stuff. The code is definitely fetching the image. But
it is not able to deliver to the browser in the form of an image. I am
trying to read the image file as binary, evident from the FILE_BINARY
command. So may be, that is causing the image to be displayed as binary. Is
there any way we can convert the binary content to jpeg/jpg content again.
This is my guess after having gone through the code again.
i spent 2 minutes working on it and read this in the manual,
the first param of imagejpeg(),
An image resource, returned by one of the image creation functions, such as
imagecreatetruecolor()<http://us.php.net/manual/en/function.imagecreatetruecolor.php>
.
so, then i tossed this together,
http://nathan.moxune.com/echoImage.php
<?php
header('Content-Type: image/jpeg');
imagejpeg(imagecreatefromjpeg('./phpLogo.jpeg'));
