INTRO

Quick and simple:

• Take a photo using the camera component

• Upload the photo to Google Drive, using the KIO4-Base64 extension to convert image to base64

• Return the file ID of the image back to the app

GOOGLE APPS SCRIPT (WEB APP)

function doPost(e) {

    var data = Utilities.base64Decode(e.parameters.data);
    var blob = Utilities.newBlob(data, e.parameters.mimetype, e.parameters.filename);
    var fileID = DriveApp.getFolderById(e.parameters.folderId).createFile(blob).getId();
    return ContentService.createTextOutput(fileID);

    }

BLOCKS

You may want to rotate and / or resize the image before uploading....

You can use this image convertor extension for that
