Hi Philippe,
for "Images to Stack", you have to show the images first.
This command uses the open images, i.e., those that are shown.
imp = IJ.openImage("
http://wsr.imagej.net/images/blobs.gif");
//imp.setTitle("blobs1.gif"); //would be nicer with this
imp.show();
imp2 = IJ.openImage("
http://wsr.imagej.net/images/blobs.gif");
imp2.show();
IJ.run(imp, "Images to Stack", "name=Stack title=[] use");
As an alternative, you can do it like the following without showing the
images:
imp = IJ.openImage("
http://wsr.imagej.net/images/blobs.gif");
is = imp.getStack();
imp2 = IJ.openImage("
http://wsr.imagej.net/images/blobs.gif");
ip = imp2.getProcessor();
is.addSlice(ip);
IJ.log("Stack size: "+is.getSize());
stackImp = new ImagePlus("The stack", is);
stackImp.show();

Usually, the easiest way is having a public method of the plugin that
gets called. If you can't modify that plugin, have a look at
ij.macro.ExtensionDescriptor
and the
ij.macro.Functions.doExt() method
to get some inspirations on how the macro extensions it can be called.
(I have no experience with this, however).
