Stitchers wikia will start adopting the new Image Galleries available from Wikia Labs.  This updated gallery design replaces traditional slideshow galleries in favor of showing a series of 8 cropped thumbnail images on a permanent basis with the option to expand the gallery to view more images if they are present.  This provides a much cleaner look than traditional galleries that could have had photos of various sizes and widths oddly fighting for prominence on a page, and allows everyone to see at a glance several photos without having to wait through a slideshow's autoscroll, or having to manually advance through each new image.  You can read more about the new Image Galleries here,

As a result of implementing this new gallery design, which is still in its beta form, modifications to any galleries must be performed in source mode.  The new galleries will not appear in either the "Classic Editor" or the Visual Editor.  Adding a picture to a gallery is relatively simple; either click the edit button at the top of a page or select Classic Editor from the drop down menu beside it and then choose the option for "Source Mode".  In the section of code pertaining to the gallery, simply type any newly uploaded photo's name into the gallery.  You can preview the results to ensure the photo has been added prior to publishing. 

For your own convenience, it is advised that when first uploading any new photo to the wiki, you appropriately name the image with a small but memorable title,  It will make adding the new image to a page much easier.

Thank you, and please let us know what you think of the new photo galleries!
