Hi JoePlay, sorry for the late reply, had a bug with the talk pages. I'm afraid I haven't had any success transplanting the code so help would be appriciated. As for the logo, I was wondering it were possible to ramp up the font size a bit? Many thanks.
I created Template:InfoboxTabber as a starting point, which you can see working at User:JoePlay/test. Feel free to use this for all your infoboxes by filling in each row's title and info, or create custom versions of the infobox with specific row titles and colors. If you decide to use that template and need more than 10 rows, feel free to add more.
As for the logo, the size limit is 250x65. The logo I showed you can't get any wider, so I made it a little taller to fill in the available space. See it in this preview.
In retrospect I think the first one you made was better, less is more and so on. With the Tabber infobox there is a slight hiccup. Our infoboxes are different from the regular Template:Infobox and I have no idea how to cleanly merge them despite experimenting with it. Any help would be appriciated, as we use this version because they automatically don't show rows with no entry in data which is very useful.
I uploaded the first logo, so you should be seeing it on the wiki.
Just so you know, Template:InfoboxTabber doesn't display any rows or images for which there is no info provided. That's what the #if: parser function does. So any row that is missing or left blank will not appear. Also, if only one image is provided, only one image (and one tab) will appear. And the same applies if two images are provided.
I created another infobox - Template:MS Infobox test - as a version of the mobile suit infobox that implements the tabber. In the example I made at User:JoePlay/test2, I only provided one image, so only one image appears.
One other thing I need to mention is that, if you want, you can specify the text that appears on each image tab by using these:
I didn't use that option on the two examples I made here, but you can see it working on the infobox at the bottom of this test page.
