Please can anyone recommend an online system for data, mainly photographs and presentation files (Powerpoint/PDF's), that allows my company members to easily access globally, possibly with their own user ID/password?

Must be able mainly to link the content in emails from the Google system to send to clients, before anyone suggests, I cannot change our system to another (from Google).

The data content we need to store could be up to 50GB and it is not that important that information is really secure, if it is then good.

Thanks in advance.

Get a domain with Google Apps

Do you have a link please?

www.google.com/apps ?

You could use Yammer - www.yammer.com

Only 5$ a month, seems like a good option!

www.idrive.com Iv found it extremely reliable.

excellent solution for teams: www.basecamphq.com

or if for files only: www.dropbox.com

dropbox is very widely used, reputable, and once installed, just works without requiring any user inputs...

also check out crashplan. its a new twist on the old idea of online backup. rather than backup to a central server, you can backup to the machines of your team members... sort of social media meets online backup!

Crashplan data on a peer machine is encrypted.

HTH

Have a look at http://usekit.com - This is a basel based startup offering web based file exchange and collaboration solutions.

Dropbox could be a good option.

GoogleApps...comes with GoogleDocs and Picasa. Both of which you can share with your users. If you collaborate, even better. It's in realtime. I speak from experience, as migrate the company I work for to GoogleApps last year. Another option is Office365.

Reputable or infamous, take your pick. . http://lxnews.org/2011/06/27/dropbox-security-breach/

You can also use Microsoft Office 365, does exactly what you want
