That seems to work best for poetry and heuristic writing. Fiction requires a sustained narrative. Of course, it can be broken at intervals. Looking at the history of literature, I would argue that formal breaks have always existed. Still, the weight is on the narrative and this textual line requires concentration.
Images work best operating at intervals or tangentially.
I would argue when the image becomes equal or superior the work will veer toward poetry. Unless, of course, the image is simply an illustration, a pantomime of action. I do believe the Web can serve as a new medium to explore and develop literary forms such as fiction and poetry and new genres. A concrete example of how the Web might influence or more boldly revitalize literature comes from the convention of frames. Frames offer many interesting alternatives for literature and, especially, I believe, fiction.
