I am not sure if someone has already made this or not, but it was far too annoying to make for me to not share it.
I made an image gallery viewer that lets you open an image tiddler (or any tiddler, but in this example they are images) and in the tiddler there are forward and back buttons that when pressed close the current image and displays the next image in the gallery. http://ooktech.com/jed/externalbrain/#Gallery The transition between images isn't very pretty, but it works well enough. The ImageDisplayViewTemplate tiddler has the view template that does most of the work, and each image has to have an order field that sets the order that they will be viewed in. I am going to see if I can just make it use a $list widget, but I haven't come up with a way to do that yet. This uses a conditional view template and the calc macro from tb5 (http://tb5.tiddlyspot.com/#calc) -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
