If you just want to use tabs in infoboxes for images, then you can simply use gallery tags once you've migrated the infobox. To clarify, you wouldn't need to do anything special when migrating the infoboxes; you would be able to add the gallery tags yourself when editing.

The Help:Infoboxes page Andrewds1021 linked has a section on how to use gallery tags ("How to use multiple images or videos"); the section does in fact include an example of code. If you're wanting a live example as well, though, check out this article from a wiki I administrate.

The template that article uses doesn't have need to 'enable' gallery tags in its code; instead, the tabbed images are implemented directly in the article itself. Just look at the beginning of the infobox's wikitext in the article:

{{Infobox album
 * image =

See? Filename|Tab Label is the format used in gallery tabs. Tabber differs (you can see an example of Tabber in-use on the same wiki here), but gallery should suffice for your needs as I understand them.

As for collapsing information in infoboxes, Groups are (as Andrewds1021 noted) the way to do it. They've linked you the section on groups on Help:Infoboxes/Tags, but have you read the section on groups on the Help:Infoboxes page itsef? It has a short section on how to make groups collapsible with screenshots of the code in action.

I too don't think there's a way to make an arbitrary number of rows collapse within just one group (without a header separating those rows from the non-collapsible rows, which I think was what you were envisioning)...but there are other ways you can try to reduce the template height?

For instance, you could organize the statistics into two groups and have one group collapsed by default. A user could open/close that second statistics grouping as they please. The Danganronpa Wiki is a good case-study for using collapsible infobox sections in abundance (in an effort to ensure users can browse the wiki without accidentally spoiling themselves).

Example: Here is their characters template. Now see it in use in a random character article; all sections except the Characteristics section are collapsed by default. You could split Statistics into two sections as well...

...Or you could have the one Statistics section and divide its contents into two Panels. Check the comments of FishTank's blog post introducing panels for some examples of Panels in action on game wikis--like how Forgotten Realms Wiki organizes the Orc's statistics by Edition. You could have one panel for half of the statistics, and another panel for the rest...
