How do I make Chrome open a file instead of downloading it?

[ss9]

When I try to open a large image, Chrome decides to save the image (without asking me), instead of opening the image in the browser. How do I change this?

I'm sure you just drag&drop it?
Plain jpeg or png should work that way, but there is a solution too!

Rightclick that image and choose 'Open with'.
If Chrome isn't in that dropdown menu, and choose 'Choose default program...'.

Then, click browse and navigate to where your Chrome is installed and choose Chrome.exe.

Mine is at E:\Google\Chrome\Application, but your might vary.
