To get the "dot" part of this funtion working, one needs to change the following line from:



$dot = $include_dot ? $dot.'' : '';

to:

$dot = $include_dot ? $dot.'.' : '';



I also recommend to change the following line from:



function image_type_to_extension($imagetype,$include_dot=true)

to:

function image_type_to_extension($imagetype,$include_dot=false)



(This so that one gets a result without the dot by default, witch is nice when one needs to compair it later on)...

Just an improvement/bugfix for the function below:

<?php

$dot = $include_dot ? $dot.'' : '';

//surely what was meant is....:

$dot = $include_dot ? '.' : '';

?>



Because otherwise $dot always will be empty.....

In case your PHP doesn't have this function, you can use this:

<?



if(!function_exists('image_type_to_extension'))

{

    function image_type_to_extension($imagetype,$include_dot=true)

    {

        if(empty($imagetype)) return false;

        $dot = $include_dot ? $dot.'' : '';

        switch($imagetype)

        {

            case IMAGETYPE_GIF     : return $dot.'gif';

            case IMAGETYPE_JPEG    : return $dot.'jpg';

            case IMAGETYPE_PNG     : return $dot.'png';

            case IMAGETYPE_SWF     : return $dot.'swf';

            case IMAGETYPE_PSD     : return $dot.'psd';

            case IMAGETYPE_WBMP    : return $dot.'wbmp';

            case IMAGETYPE_XBM     : return $dot.'xbm';

            case IMAGETYPE_TIFF_II : return $dot.'tiff';

            case IMAGETYPE_TIFF_MM : return $dot.'tiff';

            case IMAGETYPE_IFF     : return $dot.'aiff';

            case IMAGETYPE_JB2     : return $dot.'jb2';

            case IMAGETYPE_JPC     : return $dot.'jpc';

            case IMAGETYPE_JP2     : return $dot.'jp2';

            case IMAGETYPE_JPX     : return $dot.'jpf';

            case IMAGETYPE_SWC     : return $dot.'swc';

            default                : return false;

        }

    }

}
