Recommended image size for TG: Featured Post is 1070px * 470px. You seem to use another size.
Please upload an image of that size or greater size as the featured image for the post you’re using in slider.
With the TG: Featured posts slider 1 I don’t think there is any problem – it is the correct size and it features correctly on the slider at the top. The problem lies in cropping in all other places where the image is featured, like when you go inside the page.
I am using TG: Featured Posts 8 on the reviews bit, stopping its sliding function, and it is the correct size (345×265) yet its still cropped. Additionally, if you enter the post, the featured image does not fill the screen and is also cropped on the page.
The same goes for the Features section on the very bottom of the page. Here, I am using TG: Featured Posts 6 and the size is 715 x 400 px, the exact recommended size in the documentation – yet it’s still cropped. Cropping also exists when you go inside the post.
Is there possibly something wrong with the widgets? Or the way I’m embedding the featured images?
Those widgets are suitable for the design with the sidebar as shown in our demo.
If you want to manage the image according to full-width design, it needs lots of code customization, so we cannot help you out on this issue from this forum.
