Hello,
Thanks for the replies left here, actually was very imples, and as Ash said was enough to change the format to JPG image and doLogo longer worked properly.
Having said that I configured Plugin for bills and running, and soon when inaugurating this new website we can now use it in our invoices.
Just wanted to ask a question. Is it possible to include an Invoice algcódigo to incorporate a reference to payments?
My compliments and thanks.
