Is it possible to automatically upload a file from a local drive by just hovering the mouse?

Hi,

I believe someone out there would be able to help me. Any help is highly appreciated.

I'm creating a web application and one of the page is recursively scan all the files in the server's D drive and show it using a grid view.

What I want to do is to have an image tooltip preview when I hover the mouse on the name of an image file that is located on the D drive. What makes this complicated is that the browser doesn't allow me to do so for security purposes and that's understandable.

Now the option that I can think of is to automatically upload an image file in the server's D drive so that when I use JavaScript to create a preview of the image by just hovering the mouse the browser will not complain. And once the user decided to either download or just view it, the page will automatically remove the particular file to save memory.

I don't want the user to either click the upload or delete the file manually. I want it all to be automatic.

Please help me with this. I already posted related question but I re-post it to check and hope that you will be able to help me with the option that I provided above
