I have found the usage of the 'Text' object and 'Image' object easier to get this done. The 'Blank' object might be quite handy to position your dashboard objects accurately. Please see the attached sample dashboard that I have created.

Before you add the Title or Image objects, try adding a Horizontal Layout Container. I just got a result like the one you described using these steps:
- Add a Horizontal Layout container above the viz
- Add a title to the right side of the container
- Add an image to the left side.
- Add a Blank to the right of the title to get the spacing right.
