Blend Photo onto canvas for web banner

[Nzkiwis]

I have a photo taken from an iPhone. The focus object can't be cut out easily. Here's a googled example.

I need to place this onto a banner 1900x400px for example. I either end up with 

1) a photo on with the image center and middle on a gradient or painted background?

2) Photo way out of view/focus due to it's sizing?

What options / ideas are there to do somethin meaningful with this??

Content-Aware Fill is not likely to create a good background with so little background availabe, so I would recommend searching stock images sites to find »filler material« to extend the image. 

Also a strong »vignette«, effectively painting the sides black, could help.

Could I grab the last cm of the image repeat it over and over then blur the image?

or could I blend it out from there to a single colour? But do it so it looked well done?

how would I do that?

»Could I grab the last cm of the image repeat it over and over then blur the image?«

If you do so I recommend converting the image to a Smart Object and use Filter > Blur Gallery > Field Blur to create a graduated blur. 

»or could I blend it out from there to a single colour? But do it so it looked well done?«

A Solid Color Layer with a Layer Mask would be an option for that.

I'm lacking ideas. Here's an image. What can be be done make this stand out in the size I need?

Why didn’t you post the image immediately?

I have a range of images I can use, as it's my product I sell. This is just one example. I wanted to pick up some ideas on what to do so i could reuse it with others in the future.

With that image filling in the background is not that hard; it is probably too difficult for Content-Aware, though. 

So manual touch-up is likely necessary. 

Edit:

That;s flippen amazing. When a look at most of my images, there is space on either side of the centrepeice .

I assume I can do the same with something like this? even though it's not the same simple pattern?

Are you willing to give a quick step by step guide to get me started on this?

Edit > Content-Aware Fill, some touch-up and Solid Color Layers may work out here.

Nice, this is what I have.

I really don't know how you achieved that last step. Can you explain that one?

Sorry I'm very new

Layer > New Fill Layer > Solid Color 

If it has a Layer Mask fill it with black, otherwise Layer > Layer Mask > Hide All 

Then paint with white to reveal the Solid Color Layer/s at the edges.
