When you create items from your device's camera roll you can choose up to 15 images by default. This is set to this number to save too many images being selected on older or slower devices which would not be able to handle it and would crash. If you have a newer or fast device you may want to upgrade this number. To change the number of images which you can choose:
1. From the home screen go to Menu > Settings.
2. Tap Images under the General heading.
3. User the slider under the Max Upload heading to change the number of images that you can choose from your device's camera roll.
Note: The more images you choose the longer your device will take to set them up on the new item(s). Your device may time out and crash if it cannot handle the number of images you have chosen. If this happens try again with fewer images selected.
