DEC: And you get hold of it by......?

Dec :Which one?, No simple zip file then..
The following code excerpt results in no image being shown in browser. However, when I bring up the text view of the HTML (via ctrl-U on Chrome browser) and click the link from there, the image shows up. Why does the image not show up through wapp-default? 'Hello' prints as expected. Thanks in advance, Doug. (I replaced the real domain with example.com)
#!/usr/bin/tclsh source <full_path>/lib/wapp/wapp.tcl proc wapp-default { wapp-subst { <img src="http://www.example.com/IMG_1870.JPG" style="width:75%"> <br><b>Hello</b> World! } } wapp-start
dbohdan 2018-03-27: That's a consequence of Wapp's default Content Security Policy . (One of Wapp's design goals is to be secure by default .) You can use curl -v and your Web browser's Console [L1 ] [L2 ] to debug the Content Security Policy.
Here is an example of how you can configure the Content Security Policy to allow images from a certain host:
#! /usr/bin/env tclsh source wapp.tcl proc wapp-default {} { wapp-content-security-policy \ {default-src 'self'; img-src 'self' https://picsum.photos} wapp-subst { <!doctype html> <img src="https://picsum.photos/450/300" style="width:75%"> <br><b>Hello</b> World! } } wapp-start $::argv
