Question

I am using asp.net 3.5 and C#.

I have a image which I want user can download.
Like, there would be a download button or link. When user click on this link he will be prompted with a pop up to save that image to his desktop.

I have tried with

<a href ="path" > </a>

but it is opening the image in other page, I want user to be prompted to either save or view the image,

please help

Thanks in advance

You need to have another page or, better yet, an HttpHandler, that takes the image path as part of the query string or as a post parameter that will send the response with Content-Disposition set to attachment. Setting the content disposition this way will cause the browser to display the file download dialog. A slightly easier way, though it depends on the user doing something extra is simply to have the link open the image in a new page and let the user right-click on it and do a “Save As”.

<a href="/path/to/handler?image=name-of-image-file">Download</a>

or

<a href="/path/to/image" target="_blank">
    Load Image in New Window then Use Save As</a>
