[Theme:Hooray] Over-ride "Post Thumbnails"

I definitely set the Settings > Media all to 0’s, but there is still 330×249’s being created and I’m guessing it’s due to the code in functions.

Anyone know how I can over-ride this?

Well, I added the theme name because I saw other people did it. I figured my question was general enough that anyone who does theme development could possibly help.

The root of the question is over-riding the parent theme’s function in a child theme function file.

Should this question be somewhere else?

From themeforest. I have a thread on the support for the theme, however, it has not yielded any assistance.

I know that I can remove the code from the parent themes function file, but I’m trying to avoid that.

Ok, that’s fine, is there another place I should be posting on general theme development support?

I see I thought that since this website hosts documentation on Child Theming and development that perhaps it would help support general Word Press development. Not other themes, but general concepts in building and developing on wordpress using themes. But ok.

So, this can be re-created on any theme. twentytwelve for instance.

If the parent theme’s function file calls the wordpress function:
http://codex.wordpress.org/Function_Reference/set_post_thumbnail_size

And one wants to over-ride that in a child theme’s function file, is that even possible? This isn’t even really a theme dependent question, to be honest.

Yes,the function is titled differently, but it’s the same. there are other commands in there as well. I was reading that you could put something like “if function exists”, but for that method it sounded like you had to edit the parent function.php as well :\

In the twenty twelve theme. If you had

function twentytwelve_setup()
{
        /**
     *  Post Thumbnails
     */
    add_theme_support( 'post-thumbnails' );
    set_post_thumbnail_size( 800, 500, true );
    set_post_thumbnail_size( 75, 75, true );
    set_post_thumbnail_size( 330, 249, true );

}
add_action( 'after_setup_theme', 'twentytwelve_setup' );

And there were other calls in there besides thumbnail. Could one over-write that without editing parent function.php?
