The new version of the NeuroPub app has quickly turned into my main tool for visualising VBM results. I'm not even using a visualizer on the computer to view the results anymore. It's much more convenient to use the iPad. I just store the results on the Dropbox, open the Dropbox app on the iPad and then import the images to NeuroPub. Once I have all the results in my image list, it's so easy to jump between images.
There's obviously more things that could be done to simplify this procedure, like built in Dropbox support in NeuroPub. But this is really a good start.
