Does Image Manipulation class work with Blobs?

So that means I'll have to store the time of each cache in the database? Wouldn't that add to the overhead?

No you can do the check using the php file functions

Code:

$files = glob('path/to/cache/*');
foreach($files as $file)
{
   if(filemtime($file) < strtotime('-24 hour'))
   {
      unlink($file);
   }
}

I know how to output a blob as an image (you set the headers), but how would you actually save it as an image (to the cache folder)?

just put the content of the blob in the file and name it appropriately. the header setting is because php is outputted as text/html by default.

I don't quite understand. Can you please give example?

Code:

file_put_contents('path/to/cache/blobname.extension', $this->model->get_blob($id));
