You got it. The reason the logo isn't 150X150 is because somebody changed the dimensions of the wiki, as of when this thread was made, the wiki looked pretty much like Wikipedia, which uses a 150X150 logo. I guess that parameter doesn't apply any more.
As for flash objects or anything of the sort, that is definitely out of my level. If you want to talk directly to Users
Wilhelmina Will &
Saphirestar, they both have much more programming/coding skills than I do, since it was both of them that set up much of the "finishing touches" like the brown background, the logo, the non-Wikipedia layout...
If you want, I can let these two users know to expect you. If you follow my above links, just type your responses at the bottom of the text box and hit 'save page'
(EDIT: I just realized that since you have a Wikipedia user profile, you probably already know this. Please disregard the micro-management in the last sentence)
One thing, they might just want to stick with the logo they've already got, but if it coms to a vote I'll back you up, and Kor probably will too, meaning we'll get 'em 3 to 2.
