The viewer was discontinued a while back. Because most maps in modern CC3+ are based on raster artwork requiring external art files, the viewer wasn't able to display those maps without also having the same artwork available, so it no longer had the utility it used to have.

If you wish to let non-CC3+ users see your maps, I recommend just exporting them to an image or printing them to a pdf file, this is the best ways for people to see them without having to own all the artwork used.

Macros can be added to menu buttons just like any other command. In fact, many of the commands on the existing buttons are actually macros, and not built-in commands.

In general, the advice to make a hotspot is usually in connection with making a macro that is intended for a single map/map style. You generally don't want to fill your toolbar with rarely used buttons.

There shouldn't be a max limit, but I have currently set it to 25 images per page so people with slower or metered connections can still use the albums without having the entire internet thrown at them at once.

But I noticed that the gallery page itself seems to lack page navigation controls, so everything beyond the 25th gallery get hidden. Seems like something the coders of the gallery plugin forgot about and nobody noticed before now. All the galleries are there, but they're not accessible. I'll try to figure out a way to fix it when I get some time.

Yea, I think that looks much better.
