Start download on click

[htown]

I have an image on a site that I want people to be able to click on to download the higher res version of it. I am assuming there is some Javascript needed for this, if so can someone tell me what it is or where to find it and if not, how else I can accomplish this.

Thank you,
Houston

Simple HTML link pointing to a server page (ASP, PHP etc.) that retrieves the hi-res image, sets a download header and streams the image to the browser.

Alternatively, a simple link pointing to the hi-res image. This will show in the browser but the user will be able to right-click and Save As (syntax depends on browser).

I do not want a larger image showing up when you click the image, I want a dialog box that asks the user where he wants to save the file. How do you do that?

First paragraph/sentence of my previous reply. You don't do it with JavaScript.

So I have to know asp or php then to do this?

Yes. You need to know how to alter the output header and send the MIME type.

But I would ZIP the image file and tell user to download the Zipfile instead.
