Increasing Access

This feature will allow people to navigate the use of image() and upload file feature easily. More documentation increases access.

Feature enhancement details

Recently, I was working on the p5 web editor without logging in. I was trying to play with image() and trying to upload an image from my computer. However, only after a while I realized I needed to login to have the option to upload.

Either within the web editor or the image() reference page, if there is an indicator that you need to login to use the upload file feature might be helpful.
