Google now made it easier "sharing and storing" images in Picasa Web Albums by improving the image upload process. Now you'll find a smoother upload flow, the five-at-a-time limitation has been removed, and you can upload HD video, too.
To get started from Chrome, Firefox or Safari click the Upload button, select an album and then choose the images and videos you want to upload. After your images have uploaded, you will see large thumbnails where you can easily add a caption, zoom in or delete right from the upload screen.
Another easy way to upload to Picasa Web Albums is from Gallery on an Android device. For example, with Android 3.0, Honeycomb, you can capture an image or video with your tablet's camera and upload directly to Picasa Web Albums to share with friends.
