Ok. I've implemented a small change, that will hopefully fix your bug. I'm not able to verify though as I don't have a Mac to try the fix.

Please download the fix from:

http://sourceforge.net/projects/albumzipstream/files/test/albumZipStream-Fix_OSX.zip/download

replace the files and report back.

Thanks for your effort,
but sorry - still the very same effect.

not what i was hoping to hear...

I have uploaded some sample zip-files to:

https://sourceforge.net/projects/albumzipstream/files/test/Sample%20Zips/

maybe you can try which of them cause problems on your mac and which, if any, work. That would really help me to narrow down the problem.

Sure!!!

I checked -
test.zip -> test.zip.cpgz
test2.zip -> readme.test
test3.zip -> readme.test

I tried a few hours ago on a Ubuntu machine of a friend, just to check and she also couldn't unzip the zip-archive from my homepage. (http://photos.project22.org/test-2/)

Thanks very much for your assistance. Cheers

I just tried on Mac OS X 10.7.2 and I could neither expand it with the built in tool nor with "The Unarchiver" that normally gets to open "everything".

Thanks. your input and espacially your link are of great help.

I've uploaded another build to:

http://sourceforge.net/projects/albumzipstream/files/test/albumZipStream-Fix_OSX.zip/download

which will hopefully fix the problem.

Edit: just for those interested in technical info:

there were 2 problems.

1. the header of the zip caused problems on mac as the zip told to be made on OS2/HPFS filesystem, which OSX seems to have problems with.
2. there was a possible php notice thrown which was prepended to the zip and thus causing the zip file to be invalid.

seems i've missed a notice.
fixed and hopefully working version now:
http://sourceforge.net/projects/albumzipstream/files/test/albumZipStream-Fix_OSX.zip/download

YEAAAAH
now it worked.

Many many thanks from here for your efforts in making this a very useful plugin. Great

THANKS
Hein

Nice to hear. You're welcome.

I have installed this plugin and added the printAlbumZipStream(); to my album.php... it shows up just fine... the issue originally was a gettext() call to undefined..... I recompiled apache with gettext which solved that issue, now the issue I have is that when you hit the link I get the url as 404 not found. The url is actually strange as it is domain.com/plugins/zp-core/setup.php?autorun=gallery . Not sure why it is looking for zpcore folder in the plugins folder to begin with.... You can see y example on this test site....http://boatsandho.es/index.php?album=test3/ it is the second download zip link as the first is a another test and failing with the native print album zip
