Both images are in "Brand Assets" at the top of Company Basic Settings: 1. Company Logo: Go to Company Logo and click Upload Logo to select a file. Once selected, it uploads automatically. The logo appears in the business card area at the top of invitation emails, the system header, and is used for "Extract color from company logo" in Catalog layout. 2. Document Header: Go to Document Header and click Upload Image. This image prints at the top of PDFs for quotations, POs, shipping documents, and more—image only, no text fields. Without uploading, printed documents have no company header. Both accept JPG/PNG files only, maximum 5MB per file, with no crop function. To remove, click Remove. The login page uses a separate Login Page Display Image, uploaded separately in Login Subdomain Settings, JPG only.
