Linked to issue: https://github.com/odoo/odoo/issues/43745 At slide creation, as image_1920 was in readonly mode in form view when type is video, document or presentation, the field was not sent in value to the create. There is no reason to set this field readonly. If the user want to modify the thumbnail, that his responsability. This commit remove the readonly flag for slide.image_1920 field to allow computed thumbnail to be saved at slide creation.
