I create HTML files containing many photos each. Then in Firefox I Select/change div class of certain photos with <script> function classToggle(el) { el.classList.toggle("keep"); } </script> The intention then is to save and parse the edited HTML to identify the 'keep" photos. If I Save File As 'HTML complete' then file is saved WITH the class changes made by <script> and the photos are copied to sub folder. The img src is changed accordingly. This is what one would expect and hope for, but not what I am aiming for. I want to preserve the HTML changes made by <script> and leave everything else untouched. ie, don't muck with the photos. So I Save File As 'HTML only'. But the file that I get back seems to be original with the original HTML (even if I change the file name), class settings and all, not the edited version. Google Chrome seems to do the same thing. As a work around I could create the source HTML with comments of photo path/names then 'Save HTML complete', But the photos would still get copied to a sub folder which is a waste of time and possibly stessing my SSD. Not too complex solutions would be appreciated - I am not an expert. Thanks in advance.
