The Galleria slide show is an integral part of both TGG CE3 Pages as well as TTG CE3 Stage.
I love the look of the Galleria slide show. It’s clean, has smooth transitions, has an option for displaying thumbnails and you can make it just about any size you want.
In Pages, you can place it right up front on your Home page in either the Block or the Grid. On my photography site I placed it in the block, to the left of the introductory text. Other users make it take up the page width by placing the Galleria in the Grid and placing the Grid above the Block text. This can look really nice too.
CE3 Stage has a similar set up: Galleria in the block or the grid.
But sometimes you’ll get it all set up and all of a sudden, the slide show isn’t there at all. Yikes! A couple of things can cause this.
First of all, when working with Galleria you need to go to the Appearance control pane and under Staging, choose Galleria. Here is where you set all your options (probably better suited to a separate post).
One problem creeps in when you’ve decided to place the slideshow in the block. Placing it in the block is easy; just check the box for replacing the block image with the Galleria slideshow. But if you happen to also have the grid enabled AND you still have Galleria chosen for the Staging option, you’ll confuse the page and the slide show will show in neither the block nor the grid. So go back to the Appearance control pane and make sure the Grid is not displayed. If you plan on using the grid for another purpose, then that’s fine, as long as Galleria isn’t chosen as the staging option.
There are variations on this, like if you wanted to place the slideshow in the Grid above the Block but you accidentally enabled Galleria in the block.
So if you see absolutely no Galleria-like activity happening on the page, no spinning “loading” icon or anything like that, check to make sure you’re not doubly enabling Galleria.
The other Galleria gotcha happens when you see the interminable spinning of a loading icon or an error message and no slide show. This usually happens due to one or two things: file name problems or captioning problems.
So be sure that your file names contain only letters, numbers, hyphens, or underscores. And make sure your captions have no quote marks or hard returns. Because Galleria runs on Javascript, a quote mark in the caption will actually mean something to the script and will stop it from working. A hard return will do something similar. Matt’s got more on that in the Galleria section of the Stage documentation.
These two gotchas are by far the most common ailments suffered by broken Galleria slide shows, so if yours isn’t working, you now know where to look first.
