Make curved photos normal?

[OldSchool98]

Hi. Is there any program that can make curved photos normal? For example http://d32opxe1wdndeq.cloudfront.net/5d/ec/i73526365._szw1280h1280_.jpg I should really appreciate some help. I have tried to search for it but i can't find anything.

Lightroom, photoshop, gimp, instagram... All you need is a horizon adjustment.

The name depends on the software used.

Most call it "Rotate".

FYI... it's not 'curved'.... it's skewed.
