[Adding a color tint to an image]

I have imported an image (jpg) into Designer and want to simply add a color tint to the image. 

 

Currently when I try and apply it color to the image it fills the who image/container.  Reducing the opacity lightens the color but still covers the image. 

 

Adding a layer color loses the definition in the image, so that doesn't seem to work.

 

I know I have been able to do this before, but can't today for some reason.  I am sure it's v simple, so sorry to ask.

 

Any suggestions.

 

Thanks
