When attaching a picture to an EBS online class bulletin board by shooting with a smartphone, the file cannot be attached if it exceeds 2M.Most students will take a class with a computer, but the assignment will be taken with a smart phone camera.In particular, when submitting by inserting an image, if the photo size exceeds 1M, the photo often rises and stops.So, I created a camera that takes a small picture. The shooting range was also made to fit the size of A4 paper.When you shoot with this camera, the picture capacity is stored at about 0.2M per sheet.Then you can upload it directly to EBS Online Class.When you start for the first time and you dont see a photo, you need to grant permission for the camera and storage in the app permission settings.There are many ways to allow app permissions when you surf the Internet.Go to the link below for a more detailed explanation.https://sciencelove.com/2439
