lost and confused

[No_Mans_Stang]

I dont know anything about html. But i went to the admins section of vbulletin and i tried the area where it shows u how to change colors. The php is on the screen and i can use the scroll bar to choose the color i want for exampe and it changes the script, i copy the script and paste it into the area to create the changes. The stuff seemed pretty easy.

But as for graphics i didnt see where that is chnaged. Is php like java where u have to know the size of the image to insert it?
(sorry if i am not explaining my self well enough)

What do u mean by server intensive? They give out a free ubb software if u host it thru them. And, i still can not see the difference between ubb and vb. I think ubb is written in perl or c and vb is written in php (i think) so, since i dont know any of those its irrelevant. I just want some thing that is user friendly.

If we purchase a hack could we write and implement some type of hack that could be like:

if ipaddress is not (ip one), (ip two), (ip three);
then do not allow to log in

no laughing at my cheesy attempt to explain the hack (I am a psych major not a computer major)

Oh yeah and lastly do they send free demos to try out?
My boss knows I post on forums all day (gets me in trouble) but any ways because of that i am in charge of this project and i dont know what to buy. Cause I have the funny feeling I will be stuck customizing it.

Thanks
