Quote - Many JPEG files embed an ICC color profile (color space). Commonly used color profiles include sRGB and Adobe RGB. Because these color spaces use a non-linear transformation, the dynamic range of an 8-bit JPEG file is about 11 stops. However, many applications are not able to deal with JPEG color profiles and simply ignore them.

afaik, Poser does not support reading color profiles.  that's not what makes you need to linearize your texture.  if the images are  created by a digital camera or scanner, those devices use sRGB space.  if you paint a texture, you see it through an sRGB device, so in that sense, the monitor will affect your image.  but not in the sense you seem to mean. 

...

the issue is more that if it looks right on your screen, the renderer can't work with it.

in my experience, the difference between Mac and PC was easier to handle in post than the difference between GC equations and sRGB equations.  or actually, pretty much ignore and just use the same principles of making images that work in general on the web.  just like the sRGB printers and other digital devices do, in my expeience it's best to work to the specification.  at least for the raw render.

Kobaltkween, thank you so much for correcting me.  I see that I will need to do a lot more research into the fascinating topic of gamma correction on the web.  If you happen to have more favorite web links on this topic, please post them.
