E-mail attachments can be cumbersome, especially with larger files. If you're looking for a dead-simple way to share in the cloud, give Ge.tt a go.
Two clicks will upload your images, docs, zip files, etc. and generate a tidy link that you can ping over to your coworkers. They can view certain files in their browser or download whatever they need from the package.
Ge.tt storage is temporary (unless you create an account), so use it for quick transfers, not cloud archiving.
