Wordpress thumbs

I´m having, in lack of better words, a hell of a time finding out how to use an image as thumbnail on my wordpress site.

What I want, is a thumbnail on my index.php and another, or larger repesentation of the image on my single.php. The problem with the thumb, is that it is not displaying in a correct scale.

Is it possible to upload two differnt images, one thumb and one large?

Any help will be greatly appreciated:)

True. What I need is to scale the thumb correctly. As you see, the thumb is not viewing as I want it. – Hyperpedro

Okay cool, thats a simple case of setting the thumbnail size.

So in functions.php add:

set_post_thumbnail_size( 50, 50, true );

This will crop the image to the size you specify.
