WebEasy 4 cannot import HTML files. However, images from existing web sites can be re-used in WebEasy sites. You can also copy-and-paste text into your site from your web browser (or another program) by first selecting and copying the text, then adding a new text item to your web page and pressing CTRL-V while the text edit cursor is flashing to paste the text.
This functionality is available in WebEasy Professional 5. You can contact sales for upgrade information.
