Dear Johannes,

Sorry for being inaccurate, the proper File command is
File>Import...>Image Sequence as explained in the ImageJ documentation
:
http://rsbweb.nih.gov/ij/docs/menus/file.html#import

As regards a macro for opening every file in a chosen folder, try this code :

macro "Open All Files" {
DIR=getDirectory("Choose Folder");
NAMES=getFileList(DIR);
for (i=0; i<NAMES.length; i++) {
open(DIR+NAMES[i]);
}
}

Beware, the macro will throw an error and exit if something in the
folder is not recongnized as an ImageJ compatible format, so you have
to make sure you only have images in the folder.

The code is very simple, it just asks a directory (getDirectory) with
its path stored as DIR, then store an array NAMES containing all file
names in the folder DIR (getFileList), then loop on from the first to
the last element of NAMES and opens the images, which path is created
by concatenating DIR and the element NAMES[i]. Just go to
http://rsbweb.nih.gov/ij/developer/macro/macros.html and
http://rsbweb.nih.gov/ij/developer/macro/functions.html to get started
with writing simple macros, it is not complicated and quite powerful.
