Making a frontpage in Power BI?

[Jyggalag]

Dear all,

I am completely, absolutely 100% new at Power BI. This is my first official day, so please bear with me

I currently have the following Dashboard:

Now, if I insert an image I can get it it to fill all of the screen except for below the dotted line (my red arrow is pointing at it). Is there any way to remove the white layer below this dotted line so it's not there, or simply scale it down, so my picture will fill out the entire page? I hope this question makes sense, otherwise please let me know and I will try to elaborate

Secondly, I currently want to make a nice frontpage with a company logo in the middle (which I know how to do) and then a more faded version of my own company logo in the upper right hand corner (which I don't know how to do), can anybody help me with this?

Finally, if anybody knows a nice guide, youtube video or got any cool tips for making a new frontpage in the style that I described above, please let me know as well, I would greatly appreciate it!

Thank you so much everybody! I have used this forum extensively for my Excel questions and am looking very much forward to seeing what the Power BI forum can offer

Kind regards,
Jyggalag
