To get the code, just click on the All sizes button above a picture. Flickr gives you quite a few sharing options, but maybe the handiest is the embed option, which lets you paste thumbnail previews into forums, blogs, and social networking profiles such as MySpace. The reason it has tagging and notating features is so other people can find and make sense of your photos. After doing this to several of your photos from different parts of the world, check out Mappr, which will give you a visual representation of where your photos were taken on a large map. Once you've found your spot, just drag your photo from the bottom of the screen to where the map pointer is. The built-in search isn't as forgiving as your average search engine, so if you can't remember the address, try looking it up on Googleand pasting it in. The easiest way to add the location is to type it into the search box in the top right-hand corner. This will pull up a new interface with a large map. To geotag any photo, just click 'Place this photo on a map' under the Additional information box on the right-hand side of your photograph.

Geotagging is a special method of tagging photos with their location. Good note etiquette: keep notes easy to see and use by not overlapping them. You can have several different notes on the same picture, and other users can add notes to your pictures. To see them, users can just move their cursor over a picture to pull them up. The cool thing about notes is they don't get in the way if viewers don't want them.

Just like a Post-it note, you can write a quick message for others to read. This pops up a rectangle you can move around the picture and adjust in size. On any of your pictures click the Add note button above the photo. The easiest way to do this is with notes.

Say there's a really cool part of a picture you want people to notice.
