Droppics is the most powerful yet easy to use image and gallery manager for Joomla. No more need to go into the component and back into the article; create a gallery, drag and drop pictures from the article editor and you're done! Both the frontend and the backend work in the same way. This extension is really easy for beginners to manage galleries and single pictures: generate a custom sized image in one click, automatically create a custom slideshow and apply amazing effects on image and galleries.
