Sorry that I'm a little late coming in on this but would like to assure you that Serif (presumably a version of PhotoPlus) is well up to the job. I had a quick play last night with PhotoPlus X3 and following technique worked well

1) Open image
2) Create duplicate layer
3) Add a layer mask to this layer
4) Select the new layer
5) Activate "mesh warp" tool and pull the bottom corners of the image very slightly to the left until the bollards and house are vertical
6) Make background layer invisible by clicking "eye" icon
7) Select black as the foreground painting colour and paint out everything in the image that you want to to remain unaltered, making it transparent. I erased everything down to the top of the house.
8 ) Click the "eye" again to make the original layer visible.

Job done. The advantage of using layers is that this leaves the original image unaltered and nothing's lost if you mess up.

Hope this helps
