600 long side is bottom of the barrel. 2000x1333 would be above average, but a few sites offer even bigger pics. Blowing up pics just to make them look bigger is a no-no though. Clarity over high-res.
Your slideshow script/html should be flexible. You can offer medium rez pics for slideshows and high rez for download but I think if you code the page to adjust to the photo width you'd have no problems.
I prefer ZIP downloads. That way I can use a photo browsing proggie to view the photos offline. That means full screen viewing, no waiting for individual big pics to download.
