I got a free template for app portfolio. It looks like this
So I insert a screenshot (this is just a sample) and rotate it -45 degrees.
but it is nowhere right as it should be.
First I am not sure if this is really 45 degrees angle. And even worse, I have no idea how to push the image into perspective to it fits the template.
In the template, it only says "insert image here" and has no instruction on how to make it perfectly fit.
I am using Gimp. Would it be easier or better to do in Photoshop or Illustrator?
