I did few already but forgot to write about how to do option-background correctly. ^^;
Aspect ratios :
For 4:3 you simply do picture of resolution 1024x768.
For 16:10 you need to do picture of size 1229x768. Next resize it to 1024x768. Yes, it will be narrowed but after adding to skin osu! will resize it to proper look.
For 16:9 same thing as above but the size of picture need to be 1366×768. And the same, resize it to 1024x768.

On a side-off-topic note yet again because I see it didn't work out the first time, do you think positioning rankings like this is okay? Could anyone provide me a screeshot with different screen resolution (I use 1024x600) if I provide the theme?
No need, it will look the same on every resolution because osu! is adding black bars on sides for widescreen resolutions.
