# Template source folder

Place your source `.html` or `.htm` files here or in subfolders. Importing a file stores a new version in the Access database. Images are copied into that version, so later edits to source files do not change an imported snapshot. Keep private campaign artwork under `templates/local/`, which Git ignores.

The current importer accepts **well-formed HTML written as XML**. Close every tag and quote every attribute, including `<img ... />` and `<br />`. It accepts basic text, links, tables, and constrained inline `style` attributes. It rejects scripts, forms, external stylesheets, event handlers, remote images, SVG, and CSS image URLs. Image paths must be relative to the HTML file's folder and use PNG, JPEG, or GIF.

Example:

```html
<html><body>
  <h1 style="color:#17324e">9 x 12 postcards</h1>
  <p>See our local advertising options.</p>
  <img src="images/postcard.png" alt="Postcard example" width="600" />
</body></html>
```

Create the `images/postcard.png` file beside the source HTML before importing. The template preview shows imported content and images. The campaign review preview adds the sender, postal address, ad identification, and opt-out footer. Approved campaigns stay paused until explicitly resumed in the Sending tab.
