Damn! you got some skills with photoshop - I presume that is what you are using. The 'chunks' are fantastic. No problem on my side. This obviously isn't for small devices. Strictly desktop/html right.
They are big over 2mb, but once downloaded it shouldn't be a problem.
The only problem is memory 10 images on screen could bring a pc to a crawl depending on pc specs.
and of course
Download time takes awhile depending on line speed.
I've created a family photo album type thing had similar image sizes and it even worked on my moms blackberry - lol (of course I could only show 1 photo at a time, but so it shouldn't be a problem.)
