Should we go with 200 wide? Bit more bandwidth but gives us more options? 150?

We probably want a medium and a large version.

Large I'm thinking can be 1600 x 1200 and medium 400-600 ? Suggestions?

Dimensions

* The Denver Public Library Digitization and Cataloguing Program produces thumbnails that are 160 pixels in the long dimension.[5]
* The California Digital Library Guidelines for Digital Images recommend 150-200 pixels for each dimension.[6]
Picture Australia requires thumbnails to be 150 pixels in the long dimension.[7]
* The International Dunhuang Project Standards for Digitization and Image Management specifies a height of 96 pixels at 72 ppi.[8]
* DeviantArt automatically produces thumbnails that are maximum 150 pixels in the long dimension.
* Flickr automatically produces thumbnails that are a maximum 240 pixels in the long dimension, or smaller 75×75 pixels. It also applies unsharp mask to them.
Picasa automatically produces thumbnails that are a maximum 144 pixels in the long dimension, or 160×160 pixels album thumbnails.
* The term vignette is sometimes used to describe an image that is smaller than the original, larger than a thumbnail, but no more than 250 pixels in the long dimension.
