Web publishing large raster graphics?

Question

Raster graphics

Hello.
It is necessary to implement the ability to conveniently view large PNG (or JPEG) graphic files in the browser. For example, here is the solution . However, proprietary and paid. And you want:

• open source
  
• Without using Flash
  

Tell me, please, is there a solution? I did some digging with MapServer and GeoServer, but everything is very tricky there, and I did not find information anywhere whether they can be adapted to display images, not maps. And there are no more ideas. Zero information on google.
Thank you.
