PNG images appear too dark or too light

Problem

PNG images appear too dark when imported via Insert, Picture, From File into PowerPoint.

Solution

Some versions of Photoshop create PNG images with bad gamma data. There's more background information and several possible fixes outlined in this Microsoft knowledgebase article

Short version:

You can also use Glenn Randers-Pehrson's freeware PNGCrush program to repair this and several other potential problems with PNG files.

Problem

This problem was originally reported as affecting PowerPoint 2000 and images saved from PhotoShop 5 but may apply to other versions as well.

It's caused when the program that creates the PNG image sets gamma data incorrectly.
