What do you mean by "works on its own"? You can use a scripting language like PHP or ASP to streamline updating tasks. I run a PHP news script for the latest new regarding my site and it makes updating a lot more convenient. I also made some BAT files that I just double-click and they automatically upload the whole site. If you need help with either, don't hesitate to ask.

You don't want an HTML page for this.  You need an application or script on the server.  You'd need to provide details about the server you're using and what you need the application/script to do.

I'm a bit confused by two of your statements that seem to contradict each other.

>> I want to make this file work on its own.. without me needing to open it in my browser

and

>> I need it to refresh an image for example from a site

Do you mean:

a) You want a page, that is being displayed in a browser, to be automatically refreshed

or

b) The server should occasionally update an image that it is storing (eg. by fetching a new image from another site)?

The server may be Unix, but what is the web/application server (Apache? Tomcat? etc.)?

no need for viewing.. but need to request the image only... yes
 b is correct

b) The server should occasionally update an image that it is storing (eg. by fetching a new image from another site)?

the server is Apache.. :)

Hmm.  In that case, you probably want to create a PHP script or something to do this for you.  Unfortunately (in this case), I'm a Java specialist, so I'm not sure I can help you much more.  Hopefully though, this has helped to clarify your requirements so Timbo87 might be able to make some good suggestions ;-)

if I open a webpage, which for example has a javascript and has content that refreshes periodically... I want the same thing to happen from my server and continously without needing me to open the site and the HTM page.. I guess this is only possible on Windows servers maybe?

The platform (Windows or Unix) shouldn't make any difference.  In the case of JavaScript, the client is doing the refreshing.  Your requirement is that you do something similar on the server.

As I said, I mainly deal with Java, so if I was doing this, I'd probably have a servlet (or separate Java thread) running continuously to do the occasional refreshes.  Because Apache isn't a servlet container, you can't do this with a servlet.  That's why you need more input from Timbo87 or another expert that can explain how to do what you want with PHP or Perl or some other language that is (or is easily) integrated with Apache.

I'm sure that what you want to do is probably quite easy to someone who uses those languages ;-)

This is totally not my bag, but it sounds like you need to execute a script, job, or batch via a cron job -- sort of like Windows' Scheduled Tasks...

I've done this on Windows servers: scheduled a VBS script to run that performs the same steps as a web page. I'm sure the Unix world has similar functionality using cron, cgi, perl, and/or PHP...
