Being three months later, sometime in the next few days I'll refresh the backgrounds on the wikis where I'm an admin. If you want one like them or have some other idea, just say. Actually I'm not entirely certain what I'll be doing for the other ones yet--maybe something Inaba Manaka-based, but I'm not quite sure what. She wasn't around nearly as long as Meimi or Kanon so there's less to work with.
Well, you can make one background with two images from when she was a Kenshuusei and another background with a image of her in Itooshikutte Gomen ne and another in Boogie Woogie LOVE... But if you want to make a different background for each Wiki I don't really know....
I suppose there are more profile photos of her than the singles ones?
There's been some suggestions at the English wiki; maybe including other major events than just graduations, like the Buono! return and maybe the Hokkaido Kenshuusei. I'll try some stuff tonight, and after seeing what I come up with for other wikis we can see how similar/not you'd like the Spanish one to be.
I've found this a bit more time consuming and difficult, since there's more to be done manually, and unlike that one with the groups from several months ago it's a bit more complicated than lining up rectangles. :) I've done the French and Chinese ones so far, the idea being by the time I work up to the English and Spanish ones more of the kinks will be worked out.
There are more Inaba images to work with, but those group shots of the Hokkaido Kenshuusei and recent Buono! are about all there are.
OK, how about this for here? I've got a file saved with all the parts in different layers, so still easy enough to make adjustments if desired.
With the Fixed (rather than tiled) background type it's harder to be certain which parts will actually show, based on a person's screen settings and bla bla bla, but I think I've got the people on the right side positioned pretty decently so they're less likely to be cut off.
These three images show how I see it with different levels of zoom in my browser. Usually I get around the middle, but the others are some extremes. It's hard to make sure the part you actually want focused on shows. But it was actually intentional to put the Kenshuusei on bottom. I figured that if anyone was going to end up falling off screen, let it first be the lowest ranked. :)
