When I upload images and set them as featured images for my posts, they do not cover the whole screen in the slide bar section. How can I solve this issue?
Moreover, I am new to photo uploading and am confused about sizes. What is the optimal photo width/height sizes I need to use when I upload the photos? (I want to use a set size, like 710 x 335 px, and want Activello to adjust the size of the photos accordingly, based on where the photo will appear)
I hope that it is clear. I cannot post a link, as I have not launched the site yet.
Here I attach a photo to describe the issue. I used an image size larger than 1920 x 550. It adapts the photo to be put on top of the post well (fits it by having a size of 710 x 335), but not the photo to be put on the slider as seen by the grey area.
If you are using the image 1920 x 550 for the slider posts but still it is not displaying fine on your site then try regenerating thumbnails on your site using following plugin.
