Frequently asked questions about rte_ckeditor_image

Do I still need rte_ckeditor_image with CKEditor 5?

TYPO3 v12+ brings improved native image functions. In many cases, the extension is no longer needed. Gosign advises whether switching makes sense.

Why aren't images in the RTE rendered responsively?

Often a configuration problem: missing image size definitions, incorrect processing settings or CSS conflicts.
