Design decisions:

• dynamic images are stored as .jpeg files (to save memory space)
• while uploading image validation logic checks for min_width and min_height (to avoid blurred effect)
• to generate dynamic image only height value is required, width is calculated according to image aspect ratio
• storage backed is defined as DEFAULT_FILE_STORAGE = "django.core.files.storage.FileSystemStorage" (need to be changed for production)
