All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
It appears that the matter is as you mentioned in the question that the purpose of the newspaper is advertisement. Nonetheless, it has become crystal clear that the love of Muslims for the Prophet is very strong in their hearts as they demonstrated in the streets everywhere –as you know- condemning the publishing of the pictures and they boycotted the products of the country which initiated them. They also caused them a great financial loss, all perfect praise be to Allaah.
Nevertheless, we do not see any harm in visiting the site of this newspaper and vote 'No', provided the visitor is safe from being tempted by the forbidden pictures there in.
