Flickr Upload
Uploading picktures to flickr.com is easy. If you do not have a free flickr account, then you need to create one. Just go to
flickr and click the 'Create your account' button. You can use a google account if you have one.
Once logged in, click on 'Upload Photos & Video'. Next click on 'Choose Photos and Videos', and walk through the process to upload your pictures. They will automatically be resized appropriately.
After the upload is complete, it will ask you to add titles, tags and descriptions. The key step is to add tags as follows:
- wxtagged -- this indicates that this picture is of a weather station or surrounding area
- wx:metar=ktwc -- this indicates the site of which this is a picture
- wxstation -- add this tag if the picture includes the weather station.
If you had to create your account, then you must upload at least five pictures. It will also take longer for your pictures to appear (a week or so). Otherwise, the pictures should appear after 24-48 hours.
You can try to find photographs from the area surrounding the site marker by clicking on Find nearby photographs.
