editable: Img + Link

is possible this: <a href=""><img src=""></a> for editable

Yes. Use a pimcore_link editable and a pimcore_image editable.
Fill the pimcore_link in editmode and if you are not in editmode - see if it’s not empty and if it’s not empty create a link opening tag with the pimcore_link as href and a link closing tag after your pimcore_image tag.
