help with ajax image delete...

[72newbie]

I found a script online for uploading images with ajax. it all works fine, I can upload and save images to the database. I have some rudimentary php knowledge, javascript i am completely lost... at any rate here is what I have:

				if(response!="error" && response!=""){

					$('<li></li>').appendTo('#files').html('<img src="+response+" border="0" alt="" /><br />').addClass('success');
				} else{
					$('<li></li>').appendTo('#files').text(file).addClass('error');
				}

so I was thinking something like this:

				if(response!="error" && response!=""){
				Number++;
					$('<li></li>').appendTo('#files').html('<img src="+response+" border="0" alt="" /><a name="#" onclick="dev(Number)">remove</a><br />').addClass('+Number+');
				} else{
					$('<li></li>').appendTo('#files').text(file).addClass('error');
				}

is that correct so far? count the number of images and add the number to the class, then delete by the class? should i use ID? does addId work like add class? .. oh and i could use the count Number to limit the number of uploads too??

next how would i fire off my onclick? i'm so lost with javascript...

I am so lost... I am trying to upload a file, save it to the database, return the database count of images and the image url.
all that is working.
then I want to remove it if remove is clicked. I can hide the image with JavaScript but the <li> container remains. I think I will also need to return from the first ajax call the insert id. no problem.

but how do i use that returned insert id to trigger a second ajax call to delete that file if asked? here is what I have so far... I'm really lost here..

				var myString = response;
				var mySplitResult = myString.split("_8_");
				if(mySplitResult[0]=="1"){
					$('<li></li>').appendTo('#files').html('<img src="'+mySplitResult[1]+'" border="0" alt="" id="'+mySplitResult[0]+'"style=""/><br /><a name="#" onclick="fileR('+mySplitResult[0]+')">remove</a>').addClass('success');
					}
				
				if(mySplitResult[0]=="2"){
					$('<li></li>').appendTo('#files').html('<img src="'+mySplitResult[1]+'" border="0" alt="" id="'+mySplitResult[0]+'"style=""/><br /><a name="#" onclick="fileR('+mySplitResult[0]+')">remove</a>');
					document.getElementById("upload").style.display = "none";
					}				
				} else{
					$('<li></li>').appendTo('#files').text(file).addClass('error');
				}
			}
		});
		
	});
	
	
function fileR(numID)
{
var theID = numID;
$('<li></li>').document.getElementById(theID).remove('#files');
}
