Each thematic gallery is a coherent sub-collection of images related to each other by the subject theme. Though collectively they do include many of the site's images, these nine thematic galleries together do not include all 295 webberyimages. Nevertheless, while not exhaustive, the nine themes are representative and amply suggests thematic organization's power both to reveal and obscure the richness of a set of visual images.On the Thematic Galleries index page , each exhibit theme is represented by a composite image constructed from the details of three of the individual images included in that exhibit. Two of these composites are reproduced above. On the actual index page, each such composite is linked to an exhibit of thumbnails of all the individual images related by that theme.
The two exhibits represented by the composites above illustrate both how thematic exhibits can be used to group images and how exhibition concurrency can occur in this site. Anonymous Persons includes all images in the site of people the artist did not know; Musicians, all images of musicians. Such exhibits make it possible for the artist and the visitor to explore whether there are any observable common characteristic behaviors like postures, apparent signs of self-absorption, and so on, unique to members of any such group, regardless of where or when the individual images were drawn. At the same time, these two exhibits suggest how concurrency can occur. The artist is a musician and so has drawn over a thousand drawings of musicians under a wide variety of rehearsal and performance circumstances. Though many of those drawn were known to the artist, a sizeable number were not. All images of those musicians drawn but not known to the artist are exhibited concurrently in both the galleries represented above above. Finally, based entirely on 330 drawings of musicians, a subsequent site Musicians (see Websites spawned by Webberybelow), illustrates this concurrent overlap further.
