Update: added the "questionmark.png icon" in the first post in this thread. you can download it via the attachment.
Thanks, Shelley! I really like these. I have a question (for anyone that might know): Do I have to do anything beyond changing the image path for the "Show Default Post Icon" in the ACP? I keep getting a question mark for the default icon, so I guess I'm doing something wrong.
You may be using the old icon and old format path in the Thread Display options (show thread) area. Try the following (below) hopefully that will sort that out for you. The option is in the admincp .. vbulletin options >> Thread Display options (show thread) Show Default Post Icon and fill the path of the default icon you want to show which would be this icon >> .
Ooo, she's using a different ACP theme, the same one I use when I do vBulletin work in the back-end. And I say that with the least amount of sexual overtone. Seriously, I really like that shade of blue in the vB ACP.
You can change the icons in the image set folder inside your style/themes folder. If you are changing the file name of the icons then you have to modify the codes in the templates also. Search in Google for green icons, you will get in plenty.
