I know that Photoshop cannot read Tiff that are saved as Group IV compression. However, Photoshop will usually tell you that it cannot read Group IV when it gives you the error message.A company called Equalizer makes a software (debaelizer) that can convert Tiffs to jpgs and vice versa. There web site is http://www.equilibrium.com/
We looked at this software, but do not use it currenlty.
