Note: the ID’s for divs will vary from theme to theme.

It is advisable, unless you want to re-design your entire blog, to make sure the image you are going to replace the current one with is the same size.

Once you’ve created your new header, make sure it is optimised for quick loading, and upload it, either to Blogsome or the host you use for uploading images to.

In most themes, the code for the header image is in the #header div, though #top or #masthead may be used. This is the an example of the code to look for:

background-image: url(/wp-inst/wp-content/sitetemplates/minimaplus/img/masthead.jpg);

Change the location of the image to that of your own:

background-image: url(/images/imagename.jpg);

Make sure there are no ‘ ‘ or ” “ marks around the filename.
