Hi,
Please follow these steps:
1. Load a local Url into the WebView first. You only need to do this once;
2. When you call LoadHtml that contains local image, make sure you pass a local base Url. For example:
Code: C#
webView.LoadHtml(your_html, "c:/test.html");
The image won't be loaded by default because the WebView is initialized in the "Internet" security zone, and code/page in Internet zone is not allowed to access local resources. The two steps above are needed to switch it to "Local" security zone.
Please let us know if this works for you.
Thanks!
