I am new to forums business. I help my client to install the vB forums. A question to ask ? How to change the default logo of vBulletin ? Chinese forums in HK
Easiest way is to upload over the existing logo image, which by default is located here: forumdir/images/misc/vbulletin3_logo_white.gif Overwrite that file with your image and it will take its place.
Just design your logo in the same size as the VB logo... right click on the VB logo - click properties to see the size. Do your image in Photoshop or whatever and save it with the same name as the VB logo - right click to check the image name... then upload it like GWiz said and overright the original file. Check you site and if u still see the VB logo - click F-5, clear your cache and then refresh the site Cheers.
