NextGEN Gallery
Thumbnails not showing on Manage Gallery Page (17 posts)

  1. Andrewjmarino

    Again, sorry, I'm new to NextGen, but I've tried several things and haven't found the answer in the forums

    I upload a photo into a gallery
    I go to Manage Gallery page
    I cannot see the thumbnail image
    When I click 'view' it takes a very long time for the image to open
    I, obviously, need to see images of my photos to know if/where I want to use them
    How do I see the thumbnail?

    I tried
    -Edit Thumb - error message (exceed memory limit)
    -I can click 'recover' and the image appears, but I cannot rotate it (error-exceed memory limit) or click edit thumb (error-exceed...)
    -Bulk Actions - create new thumbnails
    Options Page - thumbnails -resize

    Thank you

    I have the same problem and I tried smaller images and it still didn't show my thumbnails. Any answers on what to try or where the problem might be??

    I have the same problem with new website and new server.
    My solution at the moment:
    Uninstalled NextGEN 1.7.4 and installed 1.7.0 now I can create thumbnails not automaticly.
    After uploading pictures Edit thumb - Customize thumbnail with no errors.

    My problem solved:
    This issue can be resolved by increasing the memory usage allocation at a per-plugin level for PHP applications that require more grunt than others. It’s quick and easy!

    1. Open an FTP connection to your root WordPress directory
    2. Open /wp-content/plugins/nextgen-gallery/lib/gd.thumbnail.inc.php with your favourite text editor (e.g. UltraEdit, etc.)
    3. On line #168 un-comment (remove the //) from before @ini_set('memory_limit', '128M');
    4. Save and upload changes
    5. Delete image/s that failed to generate a thumbnail and re-upload using NextGEN Gallery’s standard Upload Images feature

    Hi -

    I use Next-gen smooth and gallery - and I have the same problem - it just started yesterday on April 12, 2011. I have for 6 months been able to upload photos and have very nice slideshows as my posts.

    Yesterday and today, I upload the photographs but when I go to manage gallery, the gallery is there, and the pictures are there, but an empty box with a blue question mark is there instead of the photo. I try to recover from backup - it goes to the motions, but no picture showing, I regenerate thumbnails - no picture, I go to edit thumb and can see the thumbnail - I update, but still not showing in manage gallery or if I add the post - if seems to hang up.

    I took out the // to expand the memory limits as above, deleted the pics and reuploaded, but still the same problem.

    Can someone please suggest a fix?
    Thank you

    (I kept an older post from Monday on so something shows).

    My problem is resolved -
    I was unknowingly putting a set of periods in the title area and it was not recognizing the title to find the pictures - Thank you for help.

    I'm having issues as well. After trying all of the above suggestions, I still can't find success.

    Please help!!

    Hi Lisa -

    I do not know if your thumbnails were working and then stopped. That was my situation. The reason it stopped is because I did something different. I was putting in the title unnecessary characters so instead of titling the gallery
    the hidden meaning
    I titled it
    the hidden meaning….
    for esoteric reasons, but it was not allowing the gallery to associate my photos. Once I stopped doing that everything worked as before.
    I hope that helps

    Hey Rich,

    I upgraded to 1.7.4 and that's when my thumbnail images disappeared. Their appearance on the actual web page was hit or miss. So then I reverted back to 1.4.3 of the plugin -now it works fine.

    Spent several hours with this. But it still does not work. Three of 13 images have thumbnails. Others don't show up. Thumbs are small, 200 x 150, should not be a problem. If this were fixed, could be the perfect plugin. But I'm looking for another program that does the same thing, but works. Any ideas? Lisa, can you post the 1.4.2 version, I cannot find it elsewhere. Thanks.

    Hey Doug-

    I'd be happy to post 1.4.3... Where should I post it?

    Your solution worked beautifully. My current web hosting provider also helped out with the memory limit issue as they helped up the memory limit on the server.

    The image sizes I'm using are 1024 x XXX. XXX varied but started from 600.
