Solution 1:

I think your best choice is :

  • Clipboard Evolved

But you can also use these softwares:

  • JumpCut (Free and open source)
  • Clipmenu (As Calavera said :"ClipMenu is nice because it's free")
  • Clyppan
  • CuteClip
  • PTHPasteboard

Solution 2:

Jumpcut is the pure clipboard app. Clyppan is no longer free.

If you do not want all the images you copy to sit in clipboard then Clip Menu can be ruled out and Jumpcut works good.

There's a Jumpcut fork - Flycut. I do not see any difference from Jumpcut, except that it(Flycut) seems to be in, relatively more, active development.

Solution 3:

I'd recommend Alfred and its Powerpack for clipboard history. Aside from the actual keeping of history, you can save snippets that you use often and call them up with a combination of letters and search among recently copied texts. Alfred's interface for this is much nicer than Jumpcut's in my opinion. I haven't tried any of the others. I haven't found any application to be incompatible with Alfred either.

The price of the Powerpack might seem a little steep for just a clipboard history keeper, but Alfred can do so much more. It has become one of my most essential apps, so give it a try.
