I'm looking for more information on writeTo() function. I want to be able to change the names of resampled images for SEO purposes and I'm wondering how to properly set the the writeTo function on an extended image class:

function generateSmallimage($gd) {
$gd->writeTo("this.jpg");
$gd->resizeRatio(150,150);
return $gd;
}

The class documentation doesn't provide much direction on the actual use of the function.

EDIT

After a little more playing around with code pulled from the IMage Object I've gotten this far

function generateSmallimage($gd) {
   
    //Get asset Folder
    $folder = $this->ParentID ? $this->Parent()->Filename : ASSETS_DIR . "/";
   
    //Get Current Filename
    $filename = $this->Name;
   
    //Get Extension
    $ext = strtolower(substr($filename, strrpos($filename,'.')+1));
   
    //set new path and filename;
    $newFilename = $folder . "_resampled/my-file-name." . $ext;
         
    $smallImage = $gd->resizeRatio(150,150);
    $smallImage = $smallImage->writeTo($newFilename);
   
   
return $smallImage;
}

This will generate a resized image in the correct folder, but it still returns a link to a filename titled smallImage-originalFilename

Cheers,
