program we like is Gimp - Gnu Image Manipulating Program
wich allready can tell you that its is Programmed
open source and therefor Freeware
working with version 2.4
well decided to first tell you how to use "Heal"
later i perhaps show you more

choose heal:

( next you need to chose a pencil first - i like : "circle fuzzy" for this job)
chose a place that is simmilar to the place you wanna heal by pressing strg and klicking to that place
not gimp will take the info from this first place and will transfrom it to the place you will (klick or )slide your mouse over next
same direction you are moving your muse the selected place #1 will move
test it its very isey

Only problem is with what you did is you can easily see the wires on the second, not what they are, but there are streaks of distortion in a two lines across the clouds on the top.
