Print logo in a label

[Gilbert13]

Hi, I want to print labels with a logo in a container field. The text is fine but the logo does not appear in the label. If I change the container field by logo.png and print the lable both the text and the logo appear correctly.

Why the logo in the container field does not appear on the label and without the container field if it appears on the label?

I use a Dymo 450 Turbo printer

Thanks

I create a new layout using the envelope setting and adjust the layout to my label. 

It works.
