The Philips Device Plug-in is not installed on your computer.
Immediately after you have transferred your pictures in Windows Media Player, you should see a Philips screen pop-up. If it does not appear, then the Plug-in is probably missing. To check whether this Plug-in is available on your computer, go to Control Panel > Add or Remove Programs and check if Philips Device Plug-in is listed. If not, re-install the software from the installation CD2 or download it from www.usasupport.philips.com.
You may have disconnected your device from your computer too soon after the picture synchronization by Windows Media Player was finished.
Always wait for the Philips pop-up message to show and disappear before you disconnect your device.
Your pictures may not be in JPEG format.
Pictures in other formats cannot be transferred to your player.
The name of the folder that contain your pictures may be too long.
There is a limitation to the number of characters allowed in a folder's name. If it is over 128 characters it will not be supported.
