I am working on a pre-built theme, and it is clipping the thumbs off. It looks like it is happening in functions.php. I already checked the media and it is not checked. I want to achieve a resizing instead. The site is the-carstore.info

It is very easy to change the wordpress default thumbnail size at any time. Login to your wordpress and go to Settings->media and use the right options or change size of thumbnail with the crop option unchecked.
Then use this plugin to regenerate the thumbnails
Or if it still doesn't work, that means your theme is overriding some settings.
I would recommend creating a different size manually and then use it in your templates. Its easy. Just add the following code to your functions.php and it will allow you manual control over new size and will add it to the image size list in media upload box (the pop up shadowbox)
This is like because image size for thumbnails is defined to have hard crop mode, while you want scaling mode. See
You will need to look up size that theme uses for images, and re-register it with different cropping mode.
