But I can see the full resolution detail and even that file size loads in a couple seconds on my connection.

It looks to me that my photos at 1200 pixels wide and a resolution of about 300kb look the best to my eye on my laptop screen. I've been kicking back the resolution to around 200kb or a bit less so they load faster for those that have a slower connection.

But there's no comparison to even 200 kb to less than 100 to my eyes. Nice shots Tas.
