There are 5 copies of the same images are placed in a folder i.e. large(1024*768),medium(500*375),small(240*180),thu mnail(75*75),square(100*50) in size....
The following code upload number of Geocoded images(square size) when the page loads.I want when someone click on the any Geocoded image on the page ,it should show the large image(1024*768) of the same.And further click on the large image it must show again the square size image of the same.
Following is the actual code.It is in .js file
.


var epsg4326 = new OpenLayers.Projection("EPSG:4326");
var OSVMain = (function() {
var map, markers, map_move_timeout;
var photos = {};

updateLinks();
}

var center = OSV.getMapCenter(map);
var zoom = map.getZoom();
$('#permalink').attr('href',OSV.getURLBase()+'?lat ='+center.lat+'&lon='+center.lon+'&zoom='+zoom);
$('#kmllink').attr('href',getLocateLink('kml'));
}
function getLocateLink(format) {
var extent = OSV.getMapExtent(map);
var url = OSV.getURLBase()+'/api/photos/locate.'+format+'?bbox=';
url += [ extent.left, extent.bottom, extent.right, extent.top].join(',');
return url;
}
function mapChangeTimeout() {
map_move_timeout = null;

if( photos[p.data.id] ) {

var start = OSV.getStartLocation();
var numzoom = map.getNumZoomLevels();
if (start.zoom >= numzoom) start.zoom = numzoom - 1;
map.setCenter(start.pos.clone().transform(epsg4326 , map.getProjectionObject()), start.zoom);
OSV.setupMapEventHandlers(map);

Any suggestions ?
Thanking you

Why not just use a JQuery lightbox plugin? This is the one I'm using for my video-editing-in-Linux page:

http://net.tutsplus.com/freebies/lig...uery-lightbox/

And here's a tutorial on building one of your own:

Thanks for reply dugan.I dont want to use JQuery lightbox plugin.But can you tell me what the changes should be made in mine own code.??

Thanks

The second link is not to a premade plugin, but a tutorial on writing your own lightbox. Therefore, it has the information you want. And your code is already using JQuery anyway.

Furthermore, no-one's going to look at your code if it's formatted like that. You could start by wrapping it in CODE tags, which would preserve the indentation that your source file presumably has. In any case, the code snippet you posted looks completely unrelated to your problem: I can't see anything in there that looks like an attempt to build a lightbox.

Also, mentioning the significant amount of help that you've already had would have been nice...
