Here is my list of MaxCDN edits for my 4.5.4 store.
I have the X-Cart Banner mod, and these images MUST live in the file system for MaxCDN.
This is a collection of edits as contributed by many others here -- but here is what I am using, all in one post...
Hope this helps someone the way other posts here have helped me.

Setting Up MaxCDN -- make a CNAME record in cPanel to simplify the URL and make it looks like: cdn.domain.com (as opposed to companyname.companyname.netdna-cdn.com)

1. file: /smarty.php

FIND:

PHP Code:

$smarty->assign('ImagesDir',        $xcart_web_dir . $smarty_skin_dir . '/images');
$smarty->assign('SkinDir',          $xcart_web_dir . $smarty_skin_dir); 


REPLACE WITH:

PHP Code:

// MaxCDN - next two lines commented out
//$smarty->assign('ImagesDir',        $xcart_web_dir . $smarty_skin_dir . '/images');
//$smarty->assign('SkinDir',          $xcart_web_dir . $smarty_skin_dir);
// MaxCDN add the following
if ($_SERVER['HTTPS'] != 'on') 
{ 
$smarty->assign('ImagesDir',    "http://cdn.domain.com" . $smarty_skin_dir . '/images'); 
$smarty->assign('SkinDir',        "http://cdn.domain.com" . $smarty_skin_dir); 
$smarty->assign("AltImagesDir",    "http://cdn.domain.com/skin/books_and_magazines/images"); 
$smarty->assign("AltSkinDir",    "http://cdn.domain.com/skin/books_and_magazines"); 
} 
else 
{ 
$smarty->assign('ImagesDir',        $xcart_web_dir . $smarty_skin_dir . '/images'); 
$smarty->assign('SkinDir',          $xcart_web_dir . $smarty_skin_dir); 
}  
// END MaxCDN edit 


----------

note:
a) change "cdn.domain.com" to your cdn.domain.com
b) change /skin/books_and_magazines/ to your skin -- if you use "3-columns" - the path would be /skin/3-columns/ etc...

==================================
2. For css and js code

file: /include/templater/plugins/function.load_defer_code.php

FIND:

PHP Code:

$result = ('js' == $type)
            ? '<script type="text/javascript" src="' . $cacheWebFile . '"></script>'
            : '<link rel="stylesheet" type="text/css" href="' . $cacheWebFile . '" />'; 


REPLACE WITH:

PHP Code:

// COMMENT OUT next 3 lines for MaxCDN //
/*        
            $result = ('js' == $type)
            ? '<script type="text/javascript" src="' . $cacheWebFile . '"></script>'
            : '<link rel="stylesheet" type="text/css" href="' . $cacheWebFile . '" />';
*/            
// INSERT for MaxCDN
if ($_SERVER['HTTPS'] != 'on') {
$result = ('js' == $type)
            ? '<script type="text/javascript" src="' . str_replace("www.domain.com","cdn.domain.com",$cacheWebFile) . '"></script>'
            : '<link rel="stylesheet" type="text/css" href="' . str_replace("www.domain.com","cdn.domain.com",$cacheWebFile) . '" />';
} else {
        $result = ('js' == $type)
            ? '<script type="text/javascript" src="' . $cacheWebFile . '"></script>'
            : '<link rel="stylesheet" type="text/css" href="' . $cacheWebFile . '" />';
}
// END insert for MaxCDN 


==================================
3. FOR CATEGORY IMAGES

file: /include/templater/plugins/function.get_category_image_url.php

FIND:

return func_convert_amp(func_get_image_url($category['categoryid'], 'C', $category['image_path']));

REPLACE WITH:

return str_replace("www.domain.com","cdn.domain.com",func_convert_amp(func_get_image_url($category['categoryid'], 'C', $category['image_path'])));

==================================
4. FOR IMAGES (W, D, P, T images in file system)

file: /include/func/func.files.php

FIND:

$current_location = $current_location; 

REPLACE WITH:

PHP Code:

/** MaxCDN support */
if ($_SERVER['HTTPS'] != 'on') {
$current_location = $current_location; 
} else {
$current_location = 'http://cdn.domain.com';
}
/* END MaxCDN support */ 


==================================
5. FOR X-CART BANNER SYSTEM (A images in file system)

FILE:
/skin/common_files/modules/Banner_System/banner_rotator.tpl

FIND:

src="{$content.image_path|amp}"

REPLACE WITH:

src="{$content.image_path|amp|replace:'www.domain.com':'cdn.domain.com'}" 

ADDED on Jan 18
6. FOR T images -- I think this is needed too

file:
/common_files/product_thumbnail.tpl

FIND:

{$tmbn_url|amp}

REPLACE WITH:

{* MaxCDN edit - comment out next line *}
{* {$tmbn_url|amp} *}
{if $smarty.server.HTTPS ne "on"}
{$tmbn_url|amp|replace:'www.domain.com':'cdn.domain.com'}
{else}
{$tmbn_url|amp}
{/if}
{* END MaxCDN edit *}

7. FOR IMAGES (W, D, P, T images in file system)

I noticed that some variant images were not getting to the CDN. SO I tried using the code suggested by Phil in post #58 - this seems to work, and is probably a brute force solution. Don't know if I can remove #4?

file: /include/func/func.files.php

FIND:

PHP Code:

// image_path is an locally placed image
            return $current_location . str_replace(XC_DS, '/', substr($image_path, strlen(preg_replace('/' . preg_quote(XC_DS, '/') . '$/S', '', $xcart_dir)))); 


REPLACE WITH:

PHP Code:

// image_path is an locally placed image
            return 'http://cdn.domain.com' . str_replace(XC_DS, '/', substr($image_path, strlen(preg_replace('/' . preg_quote(XC_DS, '/') . '$/S', '', $xcart_dir)))); 


This seems to be doing the trick...
