I needed my replicas to link back to the original items when the users clicked on them. I modified my album.tpl file to force all items that are links to link back to the original. Below is a partial excerpt from my album.tpl file:
{if ($child.canContainChildren || $child.entityType == 'GalleryLinkItem')}
{assign var=frameType value="albumFrame"}
{capture assign=linkUrl}{g->url arg1="view=core.ShowItem"
arg2="itemId=`$child.id`"}{/capture}
{else}
{assign var=frameType value="itemFrame"}
{* !!!! Change Starts Here *}
{if isset($theme.guestPreviewMode) && $user.isAdmin}
{if isset($child.linkId) && $theme.guestPreviewMode == 0}
{g->text text="(linked)"}
{/if}
{/if}
{if isset($child.linkId)}
{assign var=linkId value=$child.linkId}
{else}
{assign var=linkId value=$child.id}
{/if}
{* !!!! /change. *}
{capture assign=linkUrl}{strip}
{if $theme.params.dynamicLinks == 'jump'}
{* !!!! change *}
{g->url arg1="view=core.ShowItem" arg2="itemId=`$linkId`"}
{else}
{* !!!! change *}
{g->url params=$theme.pageUrl arg1="itemId=`$linkId`"}
{/if}
{/strip}{/capture}
{/if}
It is worth mentioning that I also add the text "(linked)" above the thumbnails so that I can, in admin mode, easily identify which items are replicas/links. It does not show up otherwise.
