Assuming you have iCloud setup and on iOS7:
Select photo(s)
Click on icon with box and upwards arrow
Select iCloud
Give the stream a name
Set who to send to.

Bingo.

Doesn't send the actual photo but rather a link to it I think, i.e. a webpage with the stream where you can view/download etc. Try it.

Having had a play around, this sounds like the best/easiest way.

May have a look at Dropbox in the future for documents but iCloud sounds fine at the moment for pictures of the Missus dressing up our dog etc.

Thanks for your help and ideas everyone, much appreciated.
