Well, I certainly didn't change any name!
On the contrary, I reloaded fresh copies of the trunk from the SVN, twice, from two (apparently) different sources:
From a previous copy, I assume that the site logos should be in the folder
images, but in both case I didn't get them. All I have is 00.png, 01.png, 02.png, 03.png, 04.png, 05.png, 06.png, 07.png, 08.png, 09.png, 010.png, default.png, default_thumbnail.png, griffith.icns, griffith.ico, griffith.png, griffith.svg, griffith_win32_installer.bmp, griffith.xpm, meter00.png, meter01.png, meter02.png, meter03.png, meter04.png, meter05.png, meter06.png, meter07.png, meter08.png, meter09.png, nill.png, seen.png, stars.svg, unseen.png.
So, what am I doing wrong ?
