Hello, keith86.
I'd like to help you on the invoice issue you're having, but I need more details from it.
When you say image, are you referring to the logo on the invoice itself? Or are you referring to the entirety of the invoice?
Also, what fields did you edit on the existing invoice? I'd like to know this part so I can narrow down the issue and pinpoint which field on the invoice is having problems.
Looking forward to your reply.
