[resolved] Change header image size with CSS - Twenty Ten (4 posts)

    I want to use an image that isn't 198 by 940 (the default size for Tenty-Ten header images). I've seen a lot of posts recommending that the user change the functions.php file. I have 3 specific questions:

    1) I can't find the functions.php file. Where is it?
    2) My site is hosted by WordPress itself. I read that WordPress does not allow custom themes on sites it hosts itself. Is that why I can't find functions.php?
    3) Is it possible to change the header image size via the CSS stylesheet? How? I tried this code and it didn't work:

    #headerimg {
    margin:7px 9px 0;

    functions.php is in the theme folder, side-by-side with index.php, single.php, style.css, and all the others

    to edit it, go to the 'dashboard - appearance - editor' then selct it from the list on the right

    that explains why you can't find the functions.php - as a customer of wordpress.com, you have limited access to files.

    so forget 1) as you can't edit anything else than style.css.

    for more support see

    as the themes at wordpress.com can be quite different from 'free' themes, the best is to ask at the wordpress.com support forum http://en.forums.wordpress.com/forum/support

    Thanks. I'd suspected #2 was what was going on, but couldn't find it anywhere. Argh! Who thought changing the size of my header would be so hard?

    Since you are really just wanting a smaller image you do have another option. Upload a 940x198 image where the top half is what you want and the bottom half is (white/transparent/doesn't really matter). Then use CSS similar to this:

    #branding {

    I am not sure about the height because the branding box includes the site-title and the image. Might have to experiment a bit. But you will definitely want to adjust "#branding" instead of "#branding img" because will just flatten the image.
