Portfolio (Jetpack) looks not good on iPad

I set Jeetpack each “project” with image in evidence, if I display from PC I see it correctly, but if I see from the iPad I see the elongated images.
The site is www.sgbrasilltda.com.br (now in maintenance mode).

Another aspect is that the right of the site I see a white space that should not be there.

You can help me?

Thank you
