Images
External files only. Every image is saved in the fixed root folder
./image_saved/. Image bytes are never stored in HTML or JavaScript.
Upload destination
Select the extracted runtime root containing
index.html. The editor creates
./image_saved/, performs a real write/read test, and refuses to add an attachment unless the uploaded file is verified there.
Fixed linked-file mode:
data:, blob:, remote, and alternate-folder image sources
are rejected. The only allowed location is ./image_saved/ at the runtime root.
Links
