PNG problem

It seems like all pngs that i load that have a width less then 100 pixels become corrupted… Anyone experienced this? What could be the problem?

Im using “PNG loader library for OpenGL v1.45 (10/7/2000)”

can be downloaded at http://www.wyatt100.freeserve.co.uk/download.htm

Already fixed it… it was GL_UNPACK_ALIGNMENT that appearently defaults to 4… Didnt think of that.
