Strange behaviour with images & cgi-bin

#1 (**permalink**) 06-25-2003

Hi all,

I'm hoping someone can tell me what I'm doing wrong. I've a CGI script that
outputs HTML, a part of which is a <IMG SRC="images/whatever.gif">
construct.

The CGI page is outputting correctly, except that the images don't show up!
What am I doing wrong??

Here's the relevant area from httpd.conf:
--
<VirtualHost *:1003>
ServerName srv1.local
DocumentRoot /data/web/srv1/htdocs
Alias manual /data/web/srv1/htdocs/manual
Alias images /data/web/srv1/htdocs/images
ScriptAlias /cgi-bin/ "/data/web/srv1/cgi-bin/"
Alias /images/ "/data/web/srv1/htdocs/images/"
</VirtualHost>
--
Here's what's happening in error.log:
--
[Wed Jun 25 12:09:15 2003] [error] [client 127.0.0.1] script not found or
unable to stat: /data/web/srv1/cgi-bin/images

[Wed Jun 25 12:09:15 2003] [error] [client 127.0.0.1] script not found or
unable to stat: /data/web/srv1/cgi-bin/images
--

It looks to me as though the images are being looked for in
/data/web/srv1/cgi-bin/images, rather than where I specified
(/data/web/srv1/htdocs/images).

It also looks as though Apache is trying to treat the images as scripts
(CGI, presumably). Is this purely because of where they're being looked
for?

If it helps, I'm using SuSE 8.1 and Apache 1.3.26

Many thanks,

Garry

try setting the base href of your file - it this doesn't help you may
have to resort to specifying full path names in the cgi.

<base href="http://my/server/page" /> prior to the <head> tag tells the
server where the page is rooted, and then relative links will be based
on this root. looks to me like the page is assuming doc root is in the
cgi directory, and is trying to find images from there. telling it
otherwise, or using absolute paths for your images
(http://myserver/image/directory/image.gif), might fix this

(if all else fails, drop a simlink in your cgi directory to the images
dir, and enable follow simlinks for that dir...)

Your config should be alright.
You can also add "/" to the tag <img src="/images/whatever.gif">
It's all about path.

Hi Garry,

I'm fairly new to apache but I had the same problem... the server
was looking in htdocs as that is the server root.... you should try
changing the <IMG SRC="images/whatever.gif"> to <IMG
SRC="cgi-bin/images/whatever.gif">

We you trying to point to your images htdocs/images directory? Or
your cgi-bin/images directory?

Hope I've helped.
