Hueman Theme Not Using Proper Images in Posts

Hello everyone,

I am currently using the Hueman theme. My website is configured to have 1 sidebar on the main page, and each post has 1 sidebar on the right as well. When the site is configured this way, the featured images in posts is of size 980×450. However, the Hueman theme uses the thumbnail size 720×340, then it must upscale the image which makes it very blurry.

You can see this in action on my post, https://www.zerodayfinance.com/understanding-income-inequality-using-monopoloy. The featured image is that 720×340, but the actual image size is 980×450.

Through my debugging process, I just disabled Photon to see exactly which image thumbnail the theme loaded. Although so of my pages still use Photon, you can see the manual resize in there to the wrong size, then the theme must upscale the image which makes them extremely blurry.

I’ve always noticed that my featured images are blurry, even if I upload a 1 meg picture. Is there any way for me to easily fix this, or get it as a patch in a future update?

Thanks
