Template Editor
Using Jamroom
Fair questions, but I think if you just give it a go one time, the answers to most of those questions will fall into place.
* the images are done via a function, that function allows the admin to override the image from the admin panel.
* css set in the skin's CSS file can be used to over-ride any module css
* after making changes, running the integrity check and clearing the caches is the first steps if the changes dont show up.
* dont need to check any boxes, the over-ride works automatically.
* templates over-ridden via the skins will work the same as templates over-ridden via the template editor in the case of an update via the marketplace. (that is they will still over-ride the template and if the template has changed, the new template will need to be changed.)
