I have a web page at http://www.stockton.co.za/prince.shtml which I am unhappy with and would like to alter.
I don't like it for the following reasons:-
1) All images are loaded at inception making it quite slow.
2) It is definitely not user friendly.
What I thought of doing was to load a page of thumbnails initially and as and when any thumbnail is clicked use Ajax to retrieve the bigger image.
Now this is all well and good and quite easy to do but in addition I want the original thumbnails page to remain in place in the background and have the "bigger image" in the foreground. When the "bigger image" is in turn clicked it should disappear leaving the background "thumbnails" page ready for user interaction.

Comments please, especially on how to do this overlay thing.

I know that using other peoples software such as, Joomla / Wordpress / Drupal / RVSiteBuilder, is the easy way to go about it but it teaches me very little, other than how other peoples code works.

When I code the solution myself I have at least added a bit to my programming skills and I find programming fun and my web site is not a commercial venture but an exercise in finding out how things are done.

loading the image onclick may not be as fast as you need for hi res images, but will speed page load because most people do not click images, so only the thumbs will be required

Code not guaranteed, but may be a jumping point

i would suggest that you rather try all with css. there is some great tutorials out there with css galaries

I do not think that the css methods are going to do what I want as they all seem to require preloading everything which is exactly what I do not want to do, so I am going to start working with almostbob's suggestion and see where that gets me.

Do NOT make images expand when the mouse moves. Nothing makes me hit the BACK button faster than a page that changes when you move your mouse. It's annoying.

The user should click to get as larger image.
