Uploading larger images

There are instances where it would be interesting to feature images in a larger format than is available with a 10kb image limit. So, of course. it is possible to split up a larger image into smaller pieces that can then be reassembled in a table on a html webpage.

How would one format for such uploading? It would require uploading the the webpage and a subfolder with the image pieces. What would the webpage reference to get the pieces?

What if you zip the non-image files and directories? And then upload the individual images?
