Thanks for your input UncleCheese. At the end of the day it all comes down to the end user, which as you said MODx can be a bit cryptic and that a big part of why I am working with Silverstripe right now. Again thank you for your input on both the ImageGallery and Silversripe as a whole, it is appreciated.

...overriding the ImageGalleryPage templates...

I suppose that's the keyword. I will check my templates. If I do not find the problem I will send you the template. The gallery itself can be viewed at...

The problem was solved by changing the following lines...

<ul class="gallery-layout">
						<% if GalleryItems.NotFirstPage %>
							<% control PreviousGalleryItems %>
								<li style="display:none;"><a id="ViewLink-$ID" rel="$RelAttr" class="$ClassAttr" title="$Caption" href="$ViewLink"><img src="$ThumbnailURL" alt="$Title"/></a></li>
							<% end_control %>
						<% end_if %>
						<% control GalleryItems %>
							<li style="height:{$Top.ThumbnailSize}px;width:{$Top.ThumbnailSize}px;">
									<a id="ViewLink-$ID" rel="$RelAttr" class="$ClassAttr" title="$Caption" href="$ViewLink"><img src="$ThumbnailURL" alt="$Title"/></a>
							</li>
						<% end_control %>
						<% if GalleryItems.NotLastPage %>
							<% control NextGalleryItems %>
								<li style="display:none;"><a id="ViewLink-$ID" rel="$RelAttr" class="$ClassAttr" title="$Caption" href="$ViewLink"><img src="$ThumbnailURL" alt="$Title"/></a></li>
							<% end_control %>
						<% end_if %>
					</ul>

$GalleryLayout

I suppose that the old template code did disable some internal mechanics around the $GalleryItem - which seems to be newer?

This is a pretty good example that the separation of code and layout is not as easy as it sounds ;) Interfaces have to be stable and that is really a hard job.

Best regards & thanks for the really cool extension, your work and your help

Glad you figured it out. Yeah, that's one area of ImageGallery that I'm not especially proud of. Fortunately, I can blame the design pattern on Silverstripe's Gallery module, which is the origin of the GalleryLayoiut template variable. ImageGallery started as a rev of Gallery, so I think that technique just stuck around, and now it's just one big, ugly mega-function. Definitely on the list of things to rev.
