The imagejpeg function accepts an additional argument for a filename. If supplied, the image will be saved to disk.
To implement caching, do something like this:
Code:
if (file_exists('some_file.jpg'))
{
return true; // file exists, so display it
}
else
{
return false; // file does not exist, so generate it and save
}
