The time it takes to upload your images depends on the speed of your internet connection and how busy your ISP is at the time.  Faster internet connections will obviously be faster in uploading.

1. If on a dial-up (56K modem connection), you can expect each image to take around 15 seconds to upload (try broadband!). This means that you can upload 100 images in about 30 minutes.

1. A broadband connection with a 128KB upload rate will reduce the upload time for 100 images to about 7 minutes or with a 1Mb upload rate completing the job in under a minute!

Rest assured that as long as your Internet connection is a stable one, then once you have started the upload, you can just leave it to finish by itself as the Upload Manager Queuing feature allows you to setup another Album or do some other work (or play!) while the upload takes place in the background.
