Eric, When I run this code, I don't get the standard "single photo capture" dialog. I'm running on a Zire72 with version 2 of the Photo Library. Is there something else needed to set this up?

Users will tap a selector trigger that displays the standard "single photo capture" dialog (see capture.jpg attachment). After capturing a photo, the standard "photo confirmation" dialog is displayed to review the photo (see confirm.jpg attachment). If the save button is selected, the JPG photo data will be copied into our database tables. >From code examples, I am able to successfully capture a photo to a file stream or VFS volume using the PalmPhotoCaptureImageV2 API. See the code sample below. However, the image in the "photo confirmation" dialog is empty (whitespace) even though the image in a file stream or file in a VFS volume contains the correct picture data. What is missing to make the confirmation image work properly with the PalmPhotoCaptureImageV2 API? Thank you!
