I'm not sure that I understand exactly what you are trying to do...
Each View in IMatch has a
File Window where you can see the files in the currently selected
object (folder, category, event, ...).
Is this what you mean with "browser" or "picture view"?
The File Window is for displaying thumbnails with more or less additional information.
The
The Quick View Panel shows an enlarged view of the
file currently focused in the active File Window.
Is this what you are looking for?
And you can switch the File Window to the
Gallery Layout to concentrate on the images, showing many or just one image in the File Window.
