 +====== how to load huge images with imageJ (on windows64) ======
 +First, you need to install the "Java Runtime Environment (JRE) 5.0 Update XXX" from [[http://​java.sun.com/​javase/​downloads/​index_jdk5.jsp|sun]],​ make sure you get the "​Windows x64"​-Version from the page (It doesn'​t matter if you download the AMD64-version,​ it will work on intel)
 +
 +After you've done this, open ImageJ.cfg (in ImageJ-folder) with your favourite text editor and change it to:
 +  ​
 +  C:​\PROGRA~2\ImageJ\
 +  C:\Program Files\Java\jre1.5.0_17\bin\javaw.exe
 +  -Xmx5000m -cp C:​\PROGRA~2\ImageJ\ij.jar ij.ImageJ
 +
 +Make shure that you add the correct paths (pay attention to "​Program Files (x86)" in 8.3-Notation and stuff like that. This makes ImageJ use the 64bit-Version of Java (the 32bit-Version can still be left installed...). -Xmx5000m makes ImageJ use 5GB of RAM, so this should be more than enough.
