Another quick tip.
If you quickly need to share a screenshot or a picture and e-mail isn’t an option then you can use an online picture sharing service to do the trick. There are heaps of them including Flickr and SkyDrive but another one worth keeping in mind is TinyPic.
It’s fairly simple to use, just go to tinypic.com and choose your image to upload. You don’t need to sign up for an account in order to get going but if you find yourself using the service quite a bit then it could be worthwhile doing so.
Mind you, you can’t manually delete a photo from the site but if you contact support with the link to the photo requesting its removal or flag it as offensive then it will be deleted.
