Nice natural candid showing great rapport with the subject ('spose that's to be expected,

Idea: for those without the skills/confidence/experience to edit images like this maybe Pixalo could have an area where full size files could be uploaded so volunteers could do the editing for folk in the spirit of friendship. The resulting edited version could then be downloaded by the owner for printing! ???
