Select Linuz Iso CDVD v0.9.0 and hit configure.
This plugin has the extra ability of compressing your images to save you disk space apart from running your images for the emulator.
Click Select Iso to select the game image you want to run/compress. Once you've selected an image you can either close the config window so you can run it or press "Compress Iso" to compress it. If you selected an already compressed image you can also select "Decompress Iso" to decompress it.
Under "Compression Method" you can select either ".Z - compress faster", which will compress your image faster but make it larger or ".BZ - compress better", which will compress your image slowly but make it smaller.
Under Options you can check/uncheck "Enable Block Dump=>'ISO name.dump'". When checked, this option will create a "ISO name".dump file in the PCSX2 root folder(where pcsx2-r4600.exe is located) from the game you ran. This file is like a small iso, which is mainly used for debugging. It will store the sectors read during the execution of the game you ran, so afterwards you will be able to load the file(using "select iso" of Linuz Iso CDVD) and run it without any image/cd/dvd. Note that if the game will try to read any other sectors from the ones not included in the dump file, it will obviously stop responding.
