Is it then possible to click the image, and enlarge it? or is it just plain and simply resized with no other options?

I read somewhere that if a user posts a small image, this will be enlarged to that size, when using CSS, is this true?

edit:

Ipstenu, I tried your CSS code, and that did not work either. But this did:

#thread .post img {max-width:580px;
