Optimization and micro-optimization thoughts:

Decrease Image FileSize

This is probably the most important factor to really decrease the loading time (less to download -> faster to finish)

  • use some image optimization service like SmushIt or some local software like IrfanView
  • find out which is the best format for converting your images
  • try to lose some quality, you'd be surprised to see what 1% does sometimes with little to unpercievable loss
  • strip image MetaData/EXIF if you don't need it

WebServer & Hardware

Access times are another important factor

  • Apache is great but others might perform better for serving image files or small files (eg. Nginx/lightHTTPd)
  • tweak the webserver's config to suit your needs
  • pick a very fast storage (use RAM if possible)

Webpage

  • use a NeverEndingPage/load-on-scroll or "Click for more"
  • paginate your image sets (maybe by importance)
  • make your image containers and links shorter, strip the extension because browsers will get the filetype from the file's header, rename your files as a base(62) counter vs. the regular 1.jpg...20000.jpg (eg. <img src=Q8U>)

Look into the caching logic for the pages. The images might be able to be cached by the web server. Do you use Apache or IIS?

better to display initially 50 images and load the remaining when page scrolled. here is an example of loading page at the time of scrolling
