Abstract: A method and apparatus for receiving an image associated with an interactive service on at least one social media server, the image belonging to a group of images. The image is stored and accessing of the image by a user is detected. In response, a request with an identification of the image is sent to a back-end server to access the interactive service. Interaction messages are exchanged with the interactive service so that the interactive service associated with the image is made available to users by accessing the image.

Abstract: A computer implemented method including: maintaining, in a storage, information about one or more sets of tags, wherein each set of tags comprises two or more tags, receiving, from a user device, a request for content relating to a certain tag, wherein the request comprises an identifier, identifying, on the basis of the identifier and the information maintained in the storage, a set of tags that comprises said certain tag, and returning, to the user device, information about content relating to said certain tag and information about content relating to at least one other tag belonging to said identified set of tags.
