You only have to download your photos from your camera to your PC, and when that is done, just run PicSizer.
Why should you install PicSizer? Easy, because sometimes whn you want to send your photos to your friend, you dont need a so big picture, but a small one which can be easily viewed and weights about 150 Kb and not 2 MB.
When you have small photos, its easier and faster to share them via internet.
The process is easy, you only have to select one photo or a batch, select the new image size you want for them and press start. In just a few seconds you will ahave your new pictures ready to be shared or uploaded.
