This does not sound like a Hype problem!.
Saying that check your constraints.
Add the Image to the any,any Size class.
Then change the size class to your preferred size rep. for iPhone and or iPad.
Next use the Align tool to add 1 constraint. Horizontal in container.
Now go to the Pin tool.
Uncheck Constrain to Margins.
Click on of the pin text fields black triangles. And make sure that it is on the view rather than the margin or any other object. ( This may need to be slightly different depending on your layout but this is a basic setup)
Now click the four light red bars which will turn them a darker red. Set the numbers to what you want. These are the distances from the sides.
Click the update frame and set it to all frames.
Add the constraints.
You will need to do this for all layout class sizes you want to provide for.
Always add elements to the any,any first. Not one of the size classes or you may not see it in any other size class.
