Greetings. Is there a possibility to create a unique barcode for each invoice by invoice_number?
I have a barcode generator, it takes value of barcode and display the generated barcode in browser, for example "/bar.php?number=123" generates a barcode image for 123 value and display it in the browser. But when a try to introduce this image in invoice, like "<img src="/bar.php?number=123" width="200" height="100"> - does not appear in the invoice. Are there some suggestions?
