Spherical Mapping Correction

I am trying to find a way to distort a 2d Graphic so that it will be correct when I use spherical mapping on a sphere.

I have found an old PC photoshop plugin but nothing suitable for Mac OSX.

This link explains what I need to achieve.

Polar map corrections on a rectangular texture map so that it can be properly mapped on a sphere without seams or pinching at the poles

If anyone could point me in the right direction this would be a really help. The client really wants to this route, but I need to find a solution.

Many thanks in advance.

All versions of Photoshop have this, check Filter->Distort->Polar Coordinates.

Alternatively you can do this in Bodypaint (part of C4D) using texture remapping and projection painting (also you could use a different projection, especially if it's just a decal).
