Forgot to mention, Dropbox also comes in iOS flavors... so having easy access while mobile is quite handy. And many other iOS apps have Dropbox saving/syncing built right in.
EDIT/ and the Mac OS version is nicely integrated into Finder: menu extra, contextual menu item as well as a special toolbar menu.
I think the only limit on (free) Dropbox is the 2 gigabyte max. To go beyond that they start to charge.
EDIT/ I also like how dropbox.com is using https (secure http), and Ghostery shows no sign of web beacons there (whereas imageshack has a couple). All in all, no one needs both... and the best choice is clear (imo).
Dropbox is an application that creates a special Finder folder that automatically syncs online and between your computers. It allows you to both backup files and keep them up-to-date between systems.
Clarification, please... The above does not give me the impression that Dropbox allows you to link to stored images for, by way of example, FTM posting. If so, both Dropbox
and ImageShack may be necessary.
Edit: But I do agree with you about the relative security and goblin-free aspects of D an IS.
