Listed Property’s Main Image Size Problem

Hello everybody.

With essential real estate , I have added my properties to my web site. However , i couldn’t handle images sizes. They are not aligning on the Menu’s Properties page due to different h X w pixels or sizes. One short , one tall , etc..
How can i standardize all properties listing main images and get them proper ? What if photo quality is lower than the others ? Should i go and personally take all photos at one pixel configuration ? This is sometimes impossible.

I know that there is an edit option for main picture on adding page. I try to edit but it won’t help. Because it only allows to crop but nothing more. Is there a way to handle this issue on Worpress – Essential real estate ? Or should i do it another way or third party program ?

Thank you very much.
