  +Just by accesing the ViSH with the browser of the smartphone or tablet, and selecting the resource upload function to do upload a picture or video taken on the fly or stored in the repository. After the resource has been uploaded in the repository, any excursions can use it.

  Excursions are public objects, which can be freely reused in the classroom, blogs or LMSs by any person having access to the ViSH with a standard Internet access. But to create or modify excursions a user must register in the ViSH and become a member of the community. The ViSH terms of use (<a href="http://vishub.org/legal_notice">http://vishub.org/legal_notice</a>) must be accepted to obtain an account.

  <div class="header_text margin-top10">
  Each account has a profile where a set of tabs on the left hand side provide access to:
  
negative.code: </ul>
  </div><br>
  <div class="header_text margin-top10">
  The ViSH is a social site where users can follow other users in order to receive information about the excursions they produce. The home of a user shows the excursions created or cloned by the users followed by him. The profile of a given user has also 2 tabs on the right hand side, with the users followed by him and the users who follow him.
  </div><br>
  <div class="header_text margin-top10">
  In addition, a recommender system will highlight the most relevant content in the ViSH related with the type of content accessed, when excursions are viewed. For a registered user his profile is also taken into account in the recommendation.
  </div><br>
  <div class="header_text margin-top10">
  Each resource supports spam or content error notifications, which provide the basis for the
  control of the adequacy of excursions with the aims of the terms of use of the ViSH: useful,
  correct and good quality content.
