Hello everyone. i have a wordpress blog, and i dont know how to insert my header to my blog. the header is jpg/png file. thanks to all...
It really depends on the theme that you are using. In some there is an admin function to change the image, in others you need to edit header.php and upload and others are more complicated because the theme has other options built in.
Rightclick the old header - properties - to find where in wordpress/themes/<default or other> it is placed. Rename your new header with the same name and paste in the right place to replace the old one.
