Hi,
FeelingPink helped me to organise my photos from Japan using the Apple software "iView".
This software allows you organise your images into folders. The software then generates all the HTML to navigate between the images and reduces the image resolution to make them much smaller but still viewable through a screen. The way the HTML is built you "just" (it's never that simple) need to upload the folders and their contents to any Web space. The great thing from my point of view is you do not need to subscribe to a site with any special image management software and your viewers just enter the URL of the home/index page to be able to see your images.
If you need to amend the content of the folders you need to perform that "locally" on the Mac using iView as there are no editing tools on the Web Space - that just holds the files. For example, I have noiced that my "Osaka" folder contains some "Kyoto" images - but I won't stress over that now.
I need to create a simple index page to navigate to all the folders but you can link to two sets of images from
here .
