Photos are made to be shared, and Yahoo! Messenger has a number of features to help you enjoy sharing photos with your family, friends, and other contacts:

The Thumbnail Strip: This strip appears beneath the currently-displayed photo in the side panel of the IM window. It has a thumbnail of each photo being shared. Clicking one of the thumbnail images displays that photo at full size. The thumbnail for the current photo is in the middle of the thumbnail strip, and the strip moves as the current photo changes.

The Slider: The slider beneath the thumbnail strip lets you quickly move the strip to the right or left, changing the displayed photo to whichever one is currently in the center of the strip. During a slideshow, the slider will move as the photos change.

Slideshow: As soon as more than one photo has been added, you and your friend can view the photos as a slideshow by clicking the arrow to the left of the slider beneath the current photo. The arrow becomes a "Stop" button while the slideshow is running. You can use the pull-down list to choose a speed of "Slow," "Normal," or "Fast" for your slideshow.

Friend's View: The Friend's View, beneath the photo displayed in the IM window, shows a thumbnail of the photo currently being viewed by your friend. Click the "Friend's View" button to see the same photo displayed at full size in your IM window.

Zoom: If you want to zoom in on the current photo, just click it; to zoom out, click it again.
