New blocks positions

Support for the new blocks positions must be added to themes: if you place blocks in the bottom and do not see them, this may be because your theme is too old. Most of the times, such support can be added easily by copying the theme.html portion that inserts the center top blocks just after the <{$xoops_contents}> division, and changing the variables so the duplicated code inserts the bottom blocks (see the default theme for an example).

Templates overriding

Designers can add custom templates to their themes, and those will be used instead of the default ones. To exploit this feature, templates have to be created in subfolders of the themes duplicating the default folders structure and removing the "templates" part:

* To overload system_userinfo.html template located in modules/system/templates/system_userinfo.html you have to create your custom version in <yourthemefolder>/modules/system/system_userinfo.html
* To overload system_block_login.html template located in modules/system/templates/blocks/system_block_login.html you have to create your custom version in <yourthemefolder>/modules/system/blocks/system_block_login.html

Output resources overriding for developers

To allow theme designers to customize images or stylesheets, you have to use the new theme class and xoImgUrl templates plug-in.

* Scripts and stylesheets can be declared to XOOPS using the theme class addScript and addStylesheet methods. The theme instance is available after the inclusion of header.php by using the $xoTheme global variable, and in a template variable of the same name:
<{$xoTheme->addStylesheet('modules/newbb/style.css')}>
* Images and medias URLs have to be generated by using the xoImgUrl plug-in in your templates:
<img src="<{xoImgUrl modules/newbb/images/reply.png}>" alt="reply" />

Output resources overriding for designers

Designers can also provide custom versions of most output-related resources using a mechanism similar to the one available to templates, for modules that support this.

* To create a custom stylesheet that will replace modules/newbb/style.css, create your customized file in <yourthemefolder>/modules/newbb/style.css
* To create a custom image that will replace modules/newbb/images/reply.png, create your customized file in <yourthemefolder>/modules/newbb/images/reply.png
