MemWell gives you the option to rotate your image if you need. Simply hold your mouse cursor over the question example and a small overlay menu will appear with options to rotate your image, remove the image, and to import a new image and replace the existing image for the question.
Creating a quiz from a text import is also possible. You can create a plain text file with a '|' delimited set of questions and answers. When you import this file into MemWell it will automatically create a new card for each line in the text file.
