You have just returned from a corporate retreat or some other business event that was well-documented with several amateur photographers. Now you want to share all of these pictures amongst your co-workers. The challenge is that you want to keep them private to the participants and not plaster them all over the Internets. What to do?

Assume that your requirements are to satisfy the ultra-paranoid in the group and also find something that is dirt simple to use. You don't want to make everyone join a new social network just to see the photos; most of us have too many logins already. That leaves out most of the microblogging sites. And you don't want to have to worry that someone will click on the wrong button andinadvertentlyshare the entire photo collection with the universe, including the press, competitors and so on.

Facebook, Instagram, Google+ and many other social-networking sites aren't very good at setting up discrete group-privacy controls, so they are out of the running for our purposes. And while there are dozens of file-sharing sites such as Box.net and Evernote, the idea is to find something that is designed around uploading and sharing images.

With that in mind, we looked at the following five services:

None of these services is perfect, but they fall into two broad categories: those that have better privacy controls and those that are easier to use.

Let's look at our requirements in more detail:

First, we want a service that can create a private space that doesn't appear on search engines and can't be discovered by unauthorized users. Photobucket and Shutterfly both do this, by setting up a special URL (Photobucket.com/groupname or Groupname.shutterfly.com) for your group. In Photobucket, for example, you have three choices for each album's privacy controls: everyone can see them, no one else can see them, or you can password protect them by invitation only. The latter is perfect for this application, and you can set up an album password so that only those folks who know the password can see and download the photos. (See screenshot below.) Shutterfly has similar options with its Share Sites feature.

The problem with both Photobucket and Shutterfly is that you need to become a member to upload photos: That is fine if you havejusta few shutterbugs in your group, but if everyone wants to be able to contribute images, it can become cumbersome.
