Why does my original bitmap look so different in my render?

Hello there. I’m unfortunately a newbee to vray and i’ve tried searching for something similar to this topic but cant seem to find the answer.
I’m in the process of modelling a bathroom and when i come to render the scene my bitmap colour (in the render) varies to that of the original, could someone please help?
I’m using linear mapping, and 2 photometric lights with GI.

One other really stupid question but how would i insert/upload an image to show you what I mean?? sorry

Thank you.

an image would be veeeery usefull. there are some free image websites. or if you have your own webspace you can put it there and link here

Here’s the sticky from the General forum on where to host your images…http://www.chaosgroup.com/forum/phpBB2/viewtopic.php?t=12769

Thanks gents. You’ll have to excuse me is i’ve screwed up here but the images should be here.

you say you are using linear mapping… hve you increased or decreased the dark or light multiplyers?
