calling a php script using img src ="random.php"

Hey all,

I have a small php script that calls a random image at the following
page.
http://www.2006ymcanationals.com/random.php

IT WORKS IF I go directly to the above link.

I am trying to call that in another page so that i get a random image
the page is http://2006ymcanationals.com/index.php using <img
src="random.php">

It is not working. I have tried using the full path to the
"random.php". I have also tried naming the main page index.html and
index.php. neither work.

what am i missing? Searching these groups it looks like this should
work.

Thanks in advance.

It's hard without looking at the code.
The images seem to be different names on the page. Eg. rimage2.jpg,
rimage3.jpg, rimage4.jpg, rimage5.jpg

Actually, in your index.php page, it's not <img src="random.php">,
it's <img href="random.php">. Correct it, and everything should
work...

You're outputting HTML from your PHP-script, not the image itself.

It's the same as if you try to have <IMG SRC="whatever.html"> - I
don't think you suppose that to work (unless whatever.html actually is
a very strangely named image file, of course).

What you should be doing in your script is to output suitable headers
for the image, and pass the image through your script. Something like
this:

<?php
$img_filename = 'test.gif'; // On serverside
// The above is what you can take as random...
header('Content-type: image/gif');
// header('Content-type: '.mime_content_type($img_filename));
// Use this if your server supports it!
header('Content-length: '.filesize($img_filename));
$file_pointer = fopen($img_filename, 'rb');
fpassthru($file_pointer);
fclose($file_pointer);
exit;
?>

Your script does not return an image. It returns an HTML page that links to
an image. You cannot link to an HTML page with the <img> tag. Maybe you're
thinking of <iframe>?

You could either choose a random filename:

<img src="<?=get_random_img_name()?>">

Or make your script return an actual image:

<?
header('Content-Type: image/gif');
readfile('foo.gif');
?>

Yes this works fine for me. As I said the images seem to be displaying with
different names which indicate to me that all is working.
What images do you have in the folder? Do they look the same?

It should, given that you link to that script from the <img> tag.

You know... I'm experiencing a very similar issue.

In my case, I am building a counter script (* non-relevant reasons
below) and I have similar behavior. I call the script directly in its
own directory and it outputs the composite image fine. Calling it
from one directory higher from within an HTML file gives a broken
image.

Originally, I copied from another script that output multiple
individual gifs when the script was called. I never understood how
that was supposed to work, other than as a stand-alone script, so I
redid the code to copy each image jpg into one image that I output
from the script.

Relevant code:
<<<
//determine size of images in directory by testing the zero image
$source = $style_folder . "0." . $ext;
$img_size = @getimagesize( $source );
// $width is string length in characters
$dst_img=ImageCreate( $width * $img_size[0], $img_size[1] );

for ($i=0;$i<strlen($countstring);$i++) {
$digit=substr("$countstring",$i,1);
// Build the image URL ...
$source = $style_folder . $digit . "." . $ext;
$src_img = imagecreatefromjpeg( $source );
// $source = $base_url . $style_folder . $digit . "." . $ext;
// echo "<img src=\"$source\" border=0>";
imagecopy( $dst_img, $src_img, $i * $img_size[0], 0, 0, 0,
$img_size[0], $img_size[1]);
}

header( "Content-type: image/jpeg" );
ImageJpeg($dst_img);

exit();
<<<

And from the calling HTML:
<<<
<img src="_Counters/jpbcount.php?link=Tester&style=odometer"
height="20" align="ABSMIDDLE">
<<<

I've tried calling the script with both an <img src= and <img
href= to no avail.

Any pointers?

Thanks.

*Non-relevant rationale
I may be migrating my server over to a Linux-based hosting service
from my own Windows 2000-based server. I liberally used a CGI program
on my site and now that I may be going to a Linux-based system, I
figured I'd mimic the functionality of it in a more portable PHP
script.

Here's a working example that might help. This checks to see if a website is
up and if it is, it displays a smiley gif and if not, a not so smiley gif in
a table of smileys. Now the page doesn't wait for ALL the smileys to not
time out before displaying; rather it displays the whole table immediately
and these pop up as they finish running. Now if it would only display a
"processing" gif while we waited :>)

==== An Actual Table Row ======

<tr>
<td>Logon.net</td>
<th><img src="/frag/status.php?addr=www.logon.net" width="37"
height="20"></th>
<th><img src="/frag/status.php?addr=mail.logon.net&port=25" width="37"
height="20"></th>
<th><img src="/frag/status.php?addr=mail.logon.net&port=110" width="37"
height="20"></th>
<th><img src="/frag/status.php?addr=mail.logon.net" width="37"
height="20"></th>
<th>&nbsp;</th>
</tr>

==== status.php has to be above Doc Root ===============
