phpBB How To Custom Logo
Here is how you replace phpBB "default logo" with your own "custom logo".
Open /styles/prosilver/imageset/imageset.cfg. If your computer can't open .cfg just temporarily change the extension to .txt. Find the line img_site_logo = site_logo.gif*52*139. Change it to the below code followed by your new image demensions...
img_site_logo = custom_site_logo.gif*120*100
Upload yur new logo to /styles/prosilver/imageset/. Note or you can always just upload your new logo and name it the same as the default one. Doing so would simply overwrite the default one. Finally, Admin panel>styles>imagesets>refresh. Then hold shift and refresh your forum index.
