Hello, I want to work with the image data of a jpeg-image like in this example: https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_canvas_getimagedata2 On a webserver it works fine, but if I test locally I get an error Isn't it possible to work locally? How do I have to change the script in order to run it locally? I will work with my (young) students with javascript and would like to work locally. Best Regards
