Images attached to events have suddenly changed size?

I think I may be going a little crazy here…but..all of my images that are attached to the various Event Calendar views have suddenly changed size.

I did make a few minor changes so it’s entirely possible that I messed something up. That said I backed my site up to what it was three days ago (when I know the images fit correctly) and it did not solve the problem.

If you check out my event page you’ll notice that all the images are kind of randomly sized. I had added a function to my functions.php that forced them all to display at a medium size and they all fit perfectly in my first little column box.

Also if you go into an individual event they are all different sizes in there too and previously they were all outputting to a set size.

This is weird too…the class that’s attached to the images (in list view) seem to be missing the sizing part…
<img width="900" height="865" src="https://ashevillemusichall.com/wp-content/uploads/1685_image_original.jpg" class="attachment- size- wp-post-image" alt="" scale="0">

I’m going to look at it with fresh eyes tomorrow but if anyone else has experienced this lately any advice or solutions would be greatly appreciated.
