Best Image Format to use with Lightbox?

I recently purchased the Gnomon Texture Library and they have some
amazing textures/bumps/specular/ maps that are highly organized in
the .TIF format.

My problem is, Lightbox doesn’t seem to understand .TIF files.

What would you recommend me doing?
Making 2 copies and converting 1 copy to .jpeg?
This library is 30gb so making a double copy is tough but on the other
hand if that is what it takes to get these textures into Zbrush i will.

Also could you tell me what image format is best used in Zbrush4?
Thanks

If it were me i would make the doubles that way you always have the original for another program.
i like to use this batch converter for these type of things.
