Fixed. I've removed gl3n and libpng references from project.

Search log file examples/example1/ui.log for lines like

In examples/example1/main.d several directories are added as 
resource path
candidates

     // resource directory search paths
     string[] resourceDirs = [
         appendPath(exePath, "../../../res/"),   // for Visual D 
and DUB builds
         appendPath(exePath, "../../../res/mdpi/"),   // for 
Visual D and DUB builds
         appendPath(exePath, "../../../../res/"),// for Mono-D 
builds
         appendPath(exePath, "../../../../res/mdpi/"),// for 
Mono-D builds
		appendPath(exePath, "res/"), // when res dir is located at the 
same directory as executable
		appendPath(exePath, "../res/"), // when res dir is located at 
project directory
		appendPath(exePath, "../../res/"), // when res dir is located 
at the same directory as executable
		appendPath(exePath, "res/mdpi/"), // when res dir is located at 
the same directory as executable
		appendPath(exePath, "../res/mdpi/"), // when res dir is located 
at project directory
		appendPath(exePath, "../../res/mdpi/") // when res dir is 
located at the same directory as executable
	];

If your executable is not located in examples/example1/Debug, 
probably you add path to your directory to list of resource dirs.

Another possible reason - FreeImage.dll is found.
Try to copy FreeImage.dll from lib directory to 
examples/example1/Debug
