Access Images in a zip file without unzipping

Hi all,
I'd like to read some png-images within a zip file on my harddisk. Since I have thousands of images within hundreds of zip files, it would be extremely nice to read the image files without the need for unzipping the requested files to my harddrive). I've opened matlab's unzip.m file and realized, that it is partially written in java. I'm not very experienced with Java, but maybe some of you know a handy solution for my problem (a special java class, or a method for this 'org.apache.tools.zip.ZipFile' class unzip.m is using)
thanks, tobi

You may be able to find an external unzip utility and call it from within MATLAB using the system function. The GNU unzip seems to support the behavior you are looking for:
If you aren't very experienced with Java, I wouldn't recommend going the Java route, though I'm sure this could be done using something like what is described here:
So, I'd recommend you
system('unzip allPics.zip pic314.png');
Hope this helps!
