Hello,
The PDFSerial, as the "Attach Serial" plugin handle Joomla transactions.
It allows to print some text into the PDF or the Image.
Currently, there is no feature which allow to select a PDF template or an Image template depending the language.
While I fully understand what you want to achieve, I see potential problems if we authorize a "language" tag for the image ; because it would be very difficult for the plugin to check if the different images exists and be sure that it can work every time.
But you can see to modify the plugin in order to change how the pdf template is loaded :
Code:
$pdf_template = $this->getFilePath($params->pdf_path);
The function getFilePath need a valid file path (it checks the existence of the file in multiple folders), so you'd want to change its parameter value just before.
Regards,
