The cached images are stored as raw bytes in the Smalltalk image. The 
"seaside-top"
is returned as raw bytes by class method #seasideBanner of 
SeasidePlatformSupport .
In Squeak, the inspector is not able to display those strings of bytes.

However you can turn those bytes into images using Seaside rendering 
methods.
For instance, using file names
    cache := WACachedDocument classPool at: #Cache.
    cache do:
        [:image |
        html image width: 100 px; fileName: image fullFileName].
using raw bytes
    cache do:
        [:image |
        html image width: 100 px; document: image asMIMEDocument].
using even rawer bytes
    cache do:
        [:image |
        html image width: 100 px; document: image asMIMEDocument content].
Finally to display an image from raw bytes returned by a method
    html image document: SeasidePlatformSupport seasideBanner.
