@TIMAI2 In the following JS, can I use image picker and then pass the reference to the html file using webviewstring?
<script>
// set webviewstring in AppInventor to "<imagefilename>,altText"
// no commas in the altText !
var img = window.AppInventor.getWebViewString();
document.getElementById("myImage").src = img.split(",")[0];
document.getElementById("myImage").alt = img.split(",")[1];
</script>
