I want to put a slideshow on my website. The images need to be uploaded by the users. The WebsiteX5 dynamic objects do not permit users to add a slideshow.

Any opensource slideshows ( currently being maintained by the developers) that can be embedded , which can be edited by users independently ? I am seeing Juicebox and Cinecopa , but they are not opensource and i would prefer to host it myself. Gallery is not maintained. Piwigo - I am unable to discover embed slideshow option for WebsiteX5. 

Any advise would be much appreciated. Thanks.
