Disable Scaling of Featured Images in Blog

Hello,

I imported all my blog posts from a previous blog / template. The featured images didn’t get carried across but that’s fine I can upload these back in manually.

The problem I have having is that on my previous blog the featured images were capped at 200px in height (with a variable width). Now when I upload them into Aqua they are being stretched out of proportions both in Blog list view and also in the Blog page itself.

Is there any way to turn off this automatic scaling of featured images? I would just like the featured images to be presented in their original size.

I appreciate your help.

Thanks,
Philip.
