PNG, Why is visual studio making me download PNG files?

Question

i write and my page loads it find. When i click on the link instead of having the image show on screen it promps me to download it. Why? How can i make it display in the browser? gif and jpg both display in the browser.

-edit- i am using FireFox 3.5 there is no code that serves it, its just a link and the file exist in my folder. The link is like http://localhost:1737/a/b/file.png. IE 8 displays the png w/o making me download. I havent tried with other browsers but surely i click on direct png link in firefox on every site mine (in VS) should act the same.

If you're fetching it with HTTP, then there is a web server serving it. Look at the MIME-type when its returned, is that set correctly?

Telnet to localhost on port 1737 (not sure the syntax on Windows but IIRC try telnet localhost 1737) and type:

GET /a/b/file.png HTTP/1.0

Followed by two returns. Look at the Content-Type: field in the header. If it's not something like image/png you have a problem serving it. Firefox may have been guessing from the file name.
