UNIX for Dummies Questions & Answers

Sometimes the webserver doesn´t find a picture or there is´nt any. Then it shows a deufault picture. If i want to have diffrent pictures on diffrent catalogs if a picture doesn´t exist. The thing is that i want diffrent picture if it´s a button picture or if it´s a another picture that doesn´t exist.

Is that possible?

I don't think you can do this easily. However, www.apache.org will have on-line docs (and search capabilities) to help better answer this.

Try:

http://www.apache.org/search.html

well if an img is not avaliable you would get this gif the famous red X. apache_pb.gif


you could always swap out that gif for something you wanted in there in the first place. but that would be rather global.

I would have thought this to be an issue related to the HTML in the page, rather than a web server one because, as has already been stated, it's not something which is perceived as part of it's function (as far as I know).

Making use of the ALT property in your IMG tag to specify an alternate image to display if the primary one is not available would work just fine. It is more granular in the sense it is based on each individual page, but if you're making use of static HTML templates or better still one of the server side scripting languages to dynamically generate content, it would be flexible and most of all simple

Just my thoughts on this.

Umm... someone tell me if I'm wrong, but the ALT property of the IMG tag in HTML is for an image description, not an alternate image. I may be wrong, but I've been writing web pages for nearly 5 years and I've never heard of that implementation.

My thoughts:


Someone earlier suggested using dynamic content generation. This would be the way to go, i.e. using PHP or JSP or GGI in a more DHTML environment.

If I was going to 'dive into this problem' I would also look at the HTML return codes and see if not having an IMG returns a
status code. There are many of these status codes. However,
I don't have much faith in this approach.

The action based on the status (return) codes could have file-level
granularity, but this would require a great deal of work for a large server and I would not advise it.

The dynamic HTML method using JSP, PHP, etc. would be my
first choice.
