How are you delivering HTML file and assets to mobile devices?

Aa a zip,i have this struct:
-slide.zip
--slide.html
--assets:
---*.PNG;

so you decompress the zip,and open it,in pc as said it works,but even if a decompress it in mobile,using Zarchiver on like the downloads folder and opening the file with chrome,no images appear.

In general, the present mobile OS allow browsing only a selected local resource due to security reasons. An opened HTML file may be isolated from file systems (by using content:// URI scheme when you are using Android). If so, it cannot access to any other local assets.

So you have to find a way to open the HTML with file:/// URI scheme, or opening HTML file through Web server instead. (That is outside the scope of Marp)

Close this issue because there are no issues in the HTML output of Marp CLI. To show the correct view on mobile devices, please consider delivering slides with assets through any Web server.
