Image Resize

I am using cfscript tag to write code that resizes an image and writes it on a certain folder. See code below.

<cfscript>

myImage = ImageNew(ExpandPath(cover_url));
ImageResize(myImage,"100","","lanczos");
ImageWrite(myImage,'#ExpandPath(thumb)#/#ListLast(cover_url,"/")#');

</cfscript>

I am not so sure how I can check if the resized photo already exist, before resizing it again. If it exist, I'd like to rename the new file name so it is unique or just don't overwrite the resized copy at all.

Thanks,

Ngu

    Yes, the function is fileExists().

    Also, don't forget to scope your myImage variable.

    <cfscript>
    var myImage = "";
    myImage = ImageNew(ExpandPath(cover_url));
    ImageResize(myImage,"100","","lanczos");
    ImageWrite(myImage,'#ExpandPath(thumb)#/#ListLast(cover_url,"/")#');

    </cfscript>

    The function you're looking for is fileExists(absolute_path_to_file).

    The fileExists() function could probably help with that.
