hi
i did a fresh install for the imageGallery on Silverstripe 1.4 from svn and everything went smooth.
i renamed the default album and published, so thew page would be there and the the moderators could upload their images.

the template then rendered the previous and next buttons, although the album was empty.
after uploading one image the buttons were gone.

well thats noting that would make the earth shake, but still strange.

i slightly changed the template (see below)
but i dont think i deleted something important

ImageGalleryPage_album.ss

<div id="primaryContent">
<div class="innerpad">
		<h2>$AlbumTitle</h2>
		$GalleryLayout
		
		<% if GalleryItems.MoreThanOnePage %>
			<ul id="pagination-imagegallery">		
				<% if GalleryItems.NotFirstPage %>
					<li class="previous"><a title="<% _t('VIEWPREVIOUSPAGE','View the previous page') %>" href="$GalleryItems.PrevLink">&laquo;<% _t('PREVIOUS','Previous') %></a></li>				
				<% else %>	
					<li class="previous-off">&laquo;<% _t('PREVIOUS','Previous') %></li>
				<% end_if %>
				<% control GalleryItems.Pages %>
					<% if CurrentBool %>
						<li class="active">assadsa $PageNum</li>
					<% else %>
						<li><a href="$Link" title="<% sprintf(_t('VIEWPAGENUMBER','View page number %s'),$PageNum) %>">$PageNum</a></li>				
					<% end_if %>
				<% end_control %>
				<% if GalleryItems.NotLastPage %>
					<li class="next"><a title="<% _t('VIEWNEXTPAGE', 'View the next page') %>" href="$GalleryItems.NextLink"><% _t('NEXT','Next') %> &raquo;</a></li>
				<% else %>
					<li class="next-off"><% _t('NEXT','Next') %> &raquo;</li>				
				<% end_if %>
			</ul> 		
		<% end_if %>
	<% if Albums %>
		</div>
	<% end_if %>
</div>
