Image Gallery Link to Image File

[rettgoings]

So I have a gallery which is displaying images from an array called imgList. When they are displayed I want the user to be able to link directly to the image. Is there a simple way to do this?

The JavaScript:

//<!--

var imgList = new Array(
	"images/gallery/1.jpg",
	"images/gallery/2.jpg",
	"images/gallery/3.jpg",
	"images/gallery/5.jpg",
	"images/gallery/6.jpg",
	"images/gallery/duo.jpg"
	);

var clientData = new Array(
'',
'',
'',
'',
'',
'',
''
);

var currentMain = 0;
var currentMainT = 0;
var current_position=0;
var all_links="";

function init(){
	all_links=document.getElementById('gallery').getElementsByTagName('a');
	all_links[0].style.color="#7d3d3d";
	ShowMain(current_position);
}

function color_me(element,color){
	element.style.color=color;
}

function Prev(){
	color_me(all_links[current_position],'#000000');
	if((current_position-1)>-1){
		current_position=current_position-1;
	}
	else{
		current_position=(all_links.length-1);
	}
	ShowMain(current_position);
//	ShowMainT(current_position);
	color_me(all_links[current_position],'#7d3d3d');
}

function direct_selection(number){
	all_links[current_position].style.color="#000000";
	current_position=number;
	ShowMain(current_position);
	all_links[current_position].style.color="#7d3d3d";
}

function Next() {
	color_me(all_links[current_position],'#000000');
	if((current_position+1)<all_links.length){
		current_position++;
	}
	else{
		current_position=0;
	}
	ShowMain(current_position);
//	ShowMainT(current_position);
	color_me(all_links[current_position],'#7d3d3d');
}

function ShowMain(which){
	currentMain = which;
	currentMainT = which;
	if ( currentMain < 0 ) currentMain = 0;
	if ( currentMainT < 0 ) currentMainT = 0;
	if ( currentMain > imgList.length-1) currentMain = imgList.length-1; 
	if ( currentMainT > clientData.length-1) currentMainT = clientData.length-1;
	document.getElementById('mainImg').src = imgList[currentMain];
	document.getElementById('mainText').innerHTML = clientData[currentMainT];
	var PD = document.getElementById('Pg');
	var PD2 = document.getElementById('Pg2');
	
	document.getElementById("mainText").style.display = 'inline';
//	return false;
}

onload = function() { ShowMain(0); }
onload = function() { ShowMainT(0); }
//-->


//<!--
function preloader(){
	// counter
	var i = 0;

	// create object
	imageObj = new Image();

	// set image list
	images = new Array();
	images[0]="images/gallery/1.jpg";
	images[1]="images/gallery/2.jpg";
	images[2]="images/gallery/3.jpg";
	images[3]="images/gallery/5.jpg";
	images[4]="images/gallery/6.jpg";
	images[5]="images/gallery/duo.jpg";


	// start preloading
	for(i=0; i<=3; i++){
		imageObj.src=images[i];
	}
}
//-->

The HTML where it is displayed:

<img id="mainImg" src="images/gallery/1.jpg" style=" border: solid #7d3d3d 5px;" alt="galleryimage" />

By "link directly to the image" do you mean that, when the user clicks on the image, you want it to open in a new window showing just the image??

If so, it's trivial:

<img id="mainImg" 
       src="images/gallery/1.jpg" 
       style=" border: solid #7d3d3d 5px;" 
       alt="galleryimage" 
       onclick="window.open(this.src,'FULLIMAGE','width=800,height=600');"

/>

The width/height/whether scrollbars show/etc. is all controlled by the third argument to window.open().

If you use '_blank' instead of 'FULLIMAGE' (or any other name), then each image opens in its own new window, instead of images reusing the same popup window. Usually, that's annoying, so I'd use a name instead. But up to you.

Thanks! Thats all I needed to know to figure it out.
