How to Use Picasa as an Image Host for WordPress

1. Register for a free Google account. Google is Picasa's parent company, and you'll need a Google account to create a Picasa Web Album. From the Picasa Web Albums home page, click the blue 'Create an Account' button and follow the instructions to create your free account.
2. Create a Picasa Web Album account by creating a Google profile, which includes the 'Photos' feature. This is where you manage and update your online photo albums through Picasa. While logged into your Google account, visit the Picasa Web Albums home page at http://picasaweb.google.com. Log in using your newly created Google account. Click the 'Yes, Create My Google Profile' button and follow the on-screen instructions to create your Google profile.

3. Download and install the Picasa software onto your hard drive. Click the blue 'Free Download' button and follow the on-screen instructions to install the software onto your computer. At the end of the installation dialog, leave 'Run Picasa' checked before clicking the 'Finished' button, so that the software launches automatically.
4. Allow the Picasa software to automatically populate with all the photos on your hard drive.
5. Upload the photo you wish to use in your WordPress post to your new Picasa Web Album. Double-click on the image in the Picasa software, then click the small 'Upload' button on the bottom of the screen. Customize the display information and designate an album in which to upload the image, if you wish. Click the 'Upload' button uploading the image to the server. The software may prompt you to log in again; if so, enter your Google user name and password.
6. Copy to your computer clipboard the direct URL of the image on the Picasa servers. Click the 'View Online' button to see your newly uploaded image in your Picasa Web Album. If you're using the Firefox browser, right-click on your image and select 'Copy Image Location' to copy the direct URL to your clipboard. In Chrome, right-click and open the image in a new tab, from which you can copy the URL.
7. Insert the photo into the WordPress page or post. While editing the WordPress page document, click the 'Image Insert' button above the content field next to the words 'Upload/Insert.' Click the 'URL' tab at the top. Paste the direct image URL in the 'Image URL' field, and fill out the rest of the form with your image's information. Click the 'Insert Into Post' button when you're done to insert the image into your WordPress page or post.
8. Click the blue 'Publish' button. Your WordPress document will publish with the Picasa photo embedded in its content.
