# Thumbnails only partially generated

 * Hello,
 * When uploading images to a gallery (NextGEN Gallery), the thumbnails are not 
   generated correctly. Mostly the first couple ones are there, one partially, and
   lots of them are not generated at all.
 * It is not possible to open the images if the thumbnail is not generated.
 * I tried troubleshooting: I updated the whole page and all the plugins. I deleted
   the image cache and also deleted and reinstalled the plugin itself.
 * The problem first occured when I installed the Wordfence plugin. However I deleted
   that plugin and all connected files now and the thumbnails are still not generated
   correctly.
 * How can I fix that problem?
 * Thanks,
    Evelyne

   to see the link]_

 * Hi [@evymus](https://wordpress.org/support/users/evymus/),
 * Sometimes these problems are visible whenever the images couldn’t upload properly
   at some point, either for something that failed in the server or with the plugin.
 * First, I would like you to check our requirements and see that everything is 
   in place.
    Confirm with your hosting provider that your installation meets these
   requirements: [https://www.imagely.com/docs/requirements/](https://www.imagely.com/docs/requirements/)
 * One that you validate that everything is ok, you can try to upload a new gallery
   as a test and re-insert, check if the thumbnails work as expected.
 * To avoid problems with the server (memory issues that might have caused an interruption
   of communication), you can easily resize your photos before uploading no larger
   than 1920×1280 (It’s important that you export your images from your photo editing
   software with the sRGB color profile).
 * More information here: Image Sizes and Resolutions
    [https://www.imagely.com/docs/image-sizes-and-resolutions/](https://www.imagely.com/docs/image-sizes-and-resolutions/)
 * Note: Not sure if WordFence creates some rules in your .htaccess file, it’s wise
   to check it, just in case.
 * Please, keep us posted; we are happy to help!

 * My problem is solved now, thank you so much! I didn’t have enough storage with
   my host.
