I'm looking for a lightweight psd viewer that allows me to turn on/off layers.
I currently work at a web-design firm and at some points in the project lifetime we need to compare the resulting website with the layout designed by our graphics team. These layouts are in a single PSD with each part/component of the layout in a separate layer. Due to this the file-size catapults to +100Mb sizes sometimes which is no problem for the graphics team with their workstations ... but for us developers ...
What i'm looking for is a way to open this psd and toggle some layers without actually firing up photoshop and loading the file. I have netbeans, firefox, chrome and several other apps running simultaneously and when firing up photoshop and loading the 100Mb file the system almost grinds to a halt.
Edit: I'm using OSX
