If you've got a snipping tool, or screen shot capturing tool, you can create a jpg file that includes white space to the right of your image. And load that as a full width image in your hub capsule
I don't have a graphics program, but it's easy to import your picture into Word, and adjust it to suit. Bring up a Hub alongside your Word page and you can select the amount of white space you'll need to include to the right of your photo, (an easy way is to span the Hub with your hand,and lay that over your word page. Doesn't have to be absolutely accurate, as the Hub capsule will 'auto-fit' to maximum anyway.
To give you an idea of what I'm talking about, take a look at the base of one of my hubs (via my profile page). I've got my profile pic on the left, some type right alongside it, and white space out to the right hand edge.
It's smaller than what could be done, if you wanted to run a bigger pic, but the principle is the same. Just remember to include the text as part of the jpeg file. (You'll see that there's a minor degradation in my example. That could be eliminated if I had a graphics program, maybe you do?)
And of course, you can insert the photo capsule anywhere you want within your hub.
Give it a try, (but keep it to yourself, lol, might be something HP doesn't want to see...)
