How to Create a WordPress Header With a Picasa Photo

1. Log into WordPress. Scroll down the left side of the screen until you reach the Theme pane, then click 'Theme Options.' Hover your mouse under 'Custom Logo' to see the required dimensions -- 290-by-128 pixels, for example.
2. Navigate to the Picasa picture you want to use as your logo, then right-click on it and click 'Save Image As.' Double-click on the photo to open it within Microsoft Paint. Click the 'Resize' button in the Image pane of the 'Home' tab. Enter the dimensions WordPress specifies, then click 'OK.' Click the 'Disk' icon at the top of the screen, give your file a name and click 'Save.' Exit out of Paint.

3. Return to WordPress. Click the 'Upload Your Logo' button, browse your computer's hard drive until you find your modified Picasa picture and click 'Open.' Click 'Save Changes' at the bottom of the Theme Options screen, then visit your website in a separate tab or window to verify that the Picasa image is now your page header.
