Using a Template
TNG templates allow you to quickly give your site a professional look and feel. To use a template, just pick the one you want (see the choices at http://lythgoes.net/genealogy/templates.php), then choose the corresponding template number on the Template Settings page. Once the change is saved, the new template style will take effect.

Customizing
You may certainly customize your site beyond what the template files allow. Your default home page is index.php, and your default header and footer are topmenu.php and footer.php. Files with those names are located within each template folder. The template-specific "style" (colors, fonts and other formatting) is defined in templatestyle.css (within the "css" subfolder for each template), but if you want to change anything, it is best to make the changes in mytngstyle.css, so that your changes will not be overwritten in a future upgrade.

Simple Changes
Changes can be made by directly editing the files mentioned in the previous paragraph, but some simple changes can be made just by editing the Template Settings. Choose a template by number and you will be shown some of the key elements of the page. Changing those settings will automatically update your site, assuming that you have not customized the pages by hand already. You may make whatever manual changes you want, but if you remove any of the PHP code, these settings may no longer have any effect.

Images
If you would like to change an image, the easiest way to do that is to upload your own image with the same name as the existing image to the "img" subfolder of the template folder you're using. For best quality, you will also want to make your image the same dimensions as the existing image. You can find the dimensions by right-clicking on the image as you view it in your browser and selecting "Properties" or "View Image Info". If you must change the image dimensions, you will want to manually update them as they appear in the HTML.

Changing Your Mind
You may choose options for multiple templates, but only one will be in use at any time. If you decide later that you want a different template, just choose a new template number at the top of the Template Settings page. Setting changes you may have made for your original template will still be there if you decide to go back.
