Check if image exists?

1

Hi all

I’ve been trying to load a different image if an image doesn’t exist. How I go about it is: I using the loadVars methods, and defined an onLoad event to fire. On successful file load, it should display the associated image, and if the load fails, it should load “noImage.gif”. I have pictures p1.gif…p6.gif and the rest are missing.


for (i=0; i<10; i++){
s = "p" + i + ".gif";
fileExists=new LoadVars();
fileExists._parent=this;
fileExists.onLoad=function(success)
{
//success is true if the file exists, false if it doesnt
    if(success)
    {
        //the file exists
//nm is an existing movie container
nm.loadMovie(sImage); //and load our .swf file into it
    }
else
nm.loadMovie('noImage.gif');
}
fileExists.load(sImage); //initiate the test
}

My problem is that file load is always a success, even when the file doesn’t exist, so the else part never fires. I just see a blank where the image should be. If the image exists, it shows up as expected.

TIA

Change this line:

fileExists.onLoad=function(success)

to

fileExists.onLoad = function(success:Boolean)

If you don’t do that, it’s just a variable with a string, then it’s always true because it has a value. This way it is actually treated as a true or false statement(Boolean)
