You will need to upload a total of five photos before others can see your photos
If you upload several photos at the same time they will have to have the same tags. If you want each to
have different tags (eg. they are of different places) upload them one by one or change the tags later when your photos are published
Mark the photos 'public' so that other people can see them
It may take about several days for your photos to be visible.
Hint:
When you see your photos just double click on the ones you want to upload and they will appear on the Flickr upload list.
