Tags are like keywords or labels that you add to a photo to make it easier to find later. You can tag a photo with phrases like "catherine yosemite hiking mountain trail." Later if you look for pictures of Catherine, you can just click that tag and get all photos that have been tagged that way.
You may also have the right to add tags to your friends' photos, if you friends set that option in the privacy settings for their photos.
Here's a list of the 150 most popular tags.
One of our members, Striatic, has posted some great tips on the FlickrCentral discussion board.
Yes. It's 75 tags per photo.
If you want to add new tags to a photo that has more 75 tags, you'll need to get the number of tags under that limit first.
When you sign up for Flickr, your new account is marked as "pending," until Flickr administrators review it to make sure you aren't posting offensive images or junk downloaded from the Web. When your account is pending, your photos won't show up in public photo lists, like Everyone's Photos, or pages that show all photos tagged with a specific tag (see examples).
Flickr is a web site for you to share photos you have taken. If the images you upload aren't photos, or they are images you "borrowed," stock photos, celebrity photos, stuff that appears to be copyrighted by someone else, screenshots, nudity, or partial nudity, it's safe to assume that we have marked you as NIPSA (Not in Public Site Areas). Otherwise, your account is in the review queue and will be reviewed soon.
