Blog images and layout issue

Design help General
1

Hello, I have a blog going and use the CMS to pull data into the article page. Which includes a title, and image on a 3-row grid. However, images seem to various sizes and make the content really wonky.
Can anyone point me in the right direction? I would like the images to stay the same size as to not disrupt the layout.
