HTML Qustion...?.

Does anyone know if you can code html to first look on the users hd for example.... an image. I know IE supposedly does this by looking in the cache first, and then if not found d/l it. I'm trying to do something similiar.

Let me try to explain:

(<a href="http://www.vbworld.com/"><img src="/images/home_off.gif" width="57" height="22" border="0"></a> )

Can I take the above html code and modify it so the first place it looks for the image home_off.gif would be a folder on the users hard drive. Then if it wasn't found there it would d/l it from the appropriate url. In other words have an option for the image location.

What I'm trying to do is combine a webbrowser that I'm working on with a particular site. When the browser navigates to the site and the page is d/l...instead of having to d/l all the images for a particular page, it would get the images from a folder on the hard drive. I get the feeling this won't work, but I'd thought I'd ask

You can use a META tag or the Expires HTTP header to change the expiration date. If you set this to the future, the browser should pull it off the disk until the page expires.

<META HTTP-EQUIV="Expires" CONTENT="dategoeshere">

You would have to program the web browser from the ground up to do that. Its not worth the trouble. Would take an extreme amount of time and coding to make your own. Including parsing of the HTML and displaying colors and positioning, not to mention code to run javascript or other client scripting.

<img src="file://C:\SomeFolder\picture.jpg"> for Windows.

That's what I thought....So it's possible to look for the file on the hard drive and of course the image source can also be a URL.

Isn't there anyway to code it....maybe with Javascript?....so that it first looks on the hard drive as a source for the image, and if it's not found then d/l the image from a URL?

I suppose it would be possible, but very impractical. It would be easy if javascript had some good built in error checking functions, but unfortunatly, it does not.

So you think it's possible.....but impractical. Impractical because it might cause errors if the file isn't found on the hard drive? It seems to me the browser would treat it as any other image source and if not found it would timeout and not display an image. Of course if through code there was an alternative source for the file....I don't know?

I'm no good with Javascript....I'm not even sure what the coding would look like to try and accomplish something like this. If you find some time and are bored....see what you or anyone else for that matter can come up with.

I'd be interested in any results...
