When you press the Play mode button, the last image captured is displayed full screen with minimal exposure information. The 2 of 9 indicates that this is the second image of nine taken.

You can quickly search through stored images using the Index playback function which is activated by pressing "Down" on the 4-way controller. Nine thumbnail size images will be displayed and you can select one using the 4-way controller and then pressing the Ok button.

The Playback menu options:

Delete - Delete current, all or format

Remove Red Eyes - Corrects the red effect which appears in the eyes of a subject when using the flash

Image Advice - Provides an analysis of the image, to identify problems with focus, exposure, etc.

Preview Panorama - Displays a low-resolution preview of a selected stitched panorama image

Rotate - Rotate image 90° clockwise, may be used multiple times

Record Audio - Records up to 60 sec. of audio to be attached to a still image

Exit - Exit the menu system

You can magnify an image in Playback mode by pressing "Up" on the 4-way controller. This allows you to check images for critical focus, etc. You can then scroll around the image by pressing the OK button and using the 4-way controller.

Images captured in portrait mode are auto-rotated, thanks to the built-in orientation sensor.

You can easily take care of red-eye without having to transfer your image to a computer, thanks to the M22's in-camera red-eye removal. Going to the Image advice option will notify you if there is a possible occurrence of Red-eye, then you select Remove Red Eyes in the playback menu and it eliminates any red-eye and allows you to preview what was changed (see above), then you can opt to save it or cancel. When you save it, it overwrites the original, so if you do not want to lose the original file I would suggest copying it to your computer first.

Up to 60-second voice memos can be attached to still images and then played back through the camera's speaker.

The motion video and audio clips are played back full-screen on the LCD or a TV (when using the optional HP R-series Camera Dock.) You can record MPEG-1 320x240 movies at up to 30fps with audio, with the length determined only by the capacity of your memory card.

Pressing the Instant Share button brings up this onscreen menu. The first option lets you print an image when connected to a PictBridge compatible printer. Next is Share All Images, which allows you to share all of the images on the internal memory or the inserted memory card. Use the HP Instant Share Setup in order to use all of the Instant Share Menu features. You have to first connect the camera to your PC, then set it up by following the onscreen instructions. After you have gone through the setup, you have access to these options (E-mail destinations, Web site destinations.) These allow you to sort your images on the camera, so when you connect the camera to the computer, the software will automatically transfer the images to the selected destination.
