I tried setting transition speed, but it always reverts to the default.
I edited transition speed setting in jalbum-settings.jap to 0 but I still get a small transition speed.
The transition speed is a variable whose minimum value is 50ms, and whose maximum value is 10000ms. It's defined that way in the Java source code. You can't magically cause it to take on some value outside that range.
I would like to have no transition effect; no fading, sliding or anything.
That wouldn't appear to be an option in the skin. I have to confess to being a little mystified, however - do you seriously think that the sudden replacement of one image with another would look good? If so, this may not be the skin for you.
I don't know what the setting skin.transitionType=conveyor does or what are the alternatives.
I imagine that refers to the "slide the current image off to the left, and slide the next image in from the right" transition. But if it's not on one of the skin settings panels, it's not something you can change.
Perhaps Laza intends to provide some alternative in a future release, like a cross-fade, though it's hard to envision how that would work, given the page layout.
