this message is related to the permissions, there is info abour recursive permissions.

connect with your host via ftp and change chmod to listed directories (recursively)

make sure that you hoster allows to use php mod named GD (graphics module for php which allows to edit / change pictures).

This php module is necessary for prestashop.
