Is there any cloud system which provides image storing and also manipulates when retrieving? For example, I've 7 images on my storage and I want to build a video from this, I don't know whether it is possible or not. please suggest.
Using Cloudinary you can generate an animated GIF of multiple images and then convert this GIF to either MP4 or WebM. See -
