  • Resolved kurra


    when I upload ZIP file for the new gallery, i got the following error
    IMG_4856.jpg (Error : Unknown file format)

    I tried with (WP 3.2.1 & Nextgen 1.9.1) and (WP3.3 & Nextgen 1.9.1), got the same error.

    Then i tried with (WP3.3 and nextgen 1.9.0) and (WP 3.2.1 & Nextgen 1.9.0) and able to add zip files with out any issue.

    So looks like this issue is related to Nextgen 1.9.1

  • Can you send me this zipfile per mail, so that I can check this here ? Or if possible attach it as new issue to my GoogleCode project. I will check then this , as my own zip’s are working.


    Same thing here, with 1.9.1 nextgen and uploading a zip, it throws errors when attempting to create the images. thumbnails are not created at all (error: “unknown file type”); regular images show up on my server but are unusable – downloading and attempting to re-open in Pshop, Pshop can not recognize them. Using the same workflow I’ve always used, no other new plugins added to my WP.


    Can you send me your email address, so that i can send you the zip file. You can send me

    Thank you


    I have just sent the zip file.

    Thank you

    Find the problem, it’s only a Mac related thing, no Windows PC will create such a zip file. The fix is here :

    Next time donate me an new Mac, I will surely test this then better 🙂

    Thank you so much Alex. It works.

    How do you apply the fix? Sorry, not so good with code.


    Copy and paste that code into the file: wp-content/plugins/nextgen-gallery/admin/functions.php
