Create a lightning component which helps in creating multiple records of a related/child object at a time. Once this component is placed in a parent object record page, it should ask to choose any related object. Then, provide an option of add and delete rows, so that user can enter multiple records at a time. And on save, it should save the newly added records, update existing records and delete the removed records.

Create a visualforce page which should be launched from a case record. Once redirected to the visualforce page, provide option to take a picture, show preview and on click of Upload, save it as a file under the case record. Handle all possible validations. Display error and success messages. After saving the file, redirect back to the case record.
