Support

TYPO3 10.4.21 and bootstrap-package 11.0.3

Description

Images in "Text & Images" are always rendered/loades with a very low resolution, though the div is 1100 pixels wide, the picture is only 530 pixels wide: <img loading="lazy" src="/fileadmin/_processed_/0/d/csm_pic_BAS_aussen-05_4c7fb80c56.jpg" intrinsicsize="530x177" title="" alt="" width="530" height="177"> Why is this like that? How can I change this?
