We have images of various sizes in the library, when uploading an image of size plus something than width; the image is cut off; is there a way that the sector containing the image can be adjusted to the size of the image?
Yes, the images are fit in covered so the layout for grid preview is consistent. If the size of the image is not made consistent then the layout will go off but the Featured Image for post/page single can be made to the original size. For that please go to ‘Appearance > Customize > Additional CSS’ and Paste the below Custom CSS code.
