Loading thousands of small images onto a webpage

I'm building a thumbnail viewer for my photograph archive, and need to load thousands of photos onto a single webpage. The thumbnail images have already been downsampled from the original photo JPG via ImageMagick + MozJPEG, all fit within 100x100px, and are 1-3 KB each.

Chrome, for instance, can handle a page with 2500+ images no problem. The slow part is requesting the images, i.e., handling 2500+ HTTP requests. Does HTTP/2.0 provide additional options for streamlining requests like these?

I'd like to avoid creating chunked mosaic images that I then sprite into the webpage (I need to be able to see the filename for each image), but that's the best workaround I can think of at the moment.
