I've been changing the menu on my forum from words to pictures, and they all seem to work accept for the Private Messaging field. No matter how I try to go about saving the image, it displays an irritating message saying "You must provide a menu name". It refuses to let me click the text box to rename it, and therefore, does not save the images I am trying to use. I am using the PunBB version. I have searched my specific problem on this help forum, and none of the suggested answers are working. I have been trying under headers and navigation, and have also tried pics management. Neither works properly. Headers and navigation with its popup message, and pics management simply doesn't make it appear. In headers and navigation, the menu is set to display images only. I am at my wits end with this. It is the only capability that will not work.

Thanks in advance.

Change them here:
Administration Panel > Display > Colors & Pictures > Pics Management
Advanced Mode
First Tab

What happens after you add the image's url and press the save button?

Well, it appears to have worked this time. I'd tried it your way previously, but it's only worked this past time. Ah, well. My have been my computer acting up a bit. Thanks for the help!

Solved.
