A little bit of copy and paste work, and my Flickr page is up and running. At the moment it contains the same images in the same low resolution (400x300) as the original Brain Pics contained, but I will add more and higher quality photos soon.
I will remove the Brain Pics section from this site, and link to the Flickr site instead. For a DIY guy like me this is a big step, but Flickr offers so many advantages and features, that I decided to outsource this feature to them.
