Title: Thumbnail and Display Issues Last modified: August 21, 2016 --- # Thumbnail and Display Issues * [selym](https://wordpress.org/support/users/selym/) * (@selym) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/) * I started having minor issues a year or so ago when plugin updates would reset how a picture would display (lightbox option ?) and I would have to go apply a setting again to fix. Strange, but not a huge deal. * Then I started having issues with different sized thumbnails in the same gallery for the last few I posted. I always had 100 x 75 sized thumbnails no matter the picture orientation, then something changed. * Then my site crashed from a hardware issue. I restored the site on new hardware, but two problems remain and any input would be appreciated. * 1) Some of my galleries still have different sized thumbnails. * 2) My thumbnails are displaying one less than what is set, with the last thumbnail being put on the next line of its own. I’ve heard this could be from thumbnails that are a pixel off in size, but that does not appear to be the case in my situation. * I am using the 2013 theme from WP to fix these issues before I even attempt to activate a premium theme and possibly invite even further issues. * Any ideas? * [https://wordpress.org/plugins/nextgen-gallery/](https://wordpress.org/plugins/nextgen-gallery/) Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Contributor [photocrati](https://wordpress.org/support/users/photocrati/) * (@photocrati) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951385) * [@selym](https://wordpress.org/support/users/selym/) – You may need to regenerate your thumbnails for each of the galleries to get to the size you want to use. For existing galleries that were inserted with the IGW (formerly ATP, aka “green button”) you may need to edit and resize the thumbnails under the Customization panel. * I would also suggest clearing the image cache under Gallery > Other Options > Miscellaneous as well. * – Cais. * Thread Starter [selym](https://wordpress.org/support/users/selym/) * (@selym) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951396) * Thanks for the response Cais. * -I have tried regenerating thumbnails on those galleries with various shaped ones a number of times, but I’ll go try it now after flushing the cache. * -When I add new galleries (the last two at least), the thumbs appear to all be the same size which is good, but they are still not aligning correctly in the Twenty Thirteen theme for me. If I set 6 images across, I get 5, then one on the next line. If I set 5 images across, I get 4, then one on the next line. * -Should we not be using the green button to add galleries? (and if not, how should we be?) To be honest, I always used the nggallery id shortcode until the plugin changed and didn’t display the gallery id right after you added it, which is when I started using the green button inside a new post. * Plugin Contributor [photocrati](https://wordpress.org/support/users/photocrati/) * (@photocrati) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951397) * [@selym](https://wordpress.org/support/users/selym/) – Using the green button is generally the best choice as it is simpler and easier to use than having to construct a shortcode. * As it is, it reads as though you have set the NextGEN Basic Thumbnail display to use the “gallery.php” template … set it to no template and see if the layout displays as expected. * Thanks! * – Cais. * Thread Starter [selym](https://wordpress.org/support/users/selym/) * (@selym) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951398) * fyi, on certain galleries if I delete the thumbnails and create new (after flushing cache), some of them will still recreate in random sizes. * Thread Starter [selym](https://wordpress.org/support/users/selym/) * (@selym) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951399) * that response was posted before I read your last reply, so I’ll go check that setting and follow up. Thank you. * Thread Starter [selym](https://wordpress.org/support/users/selym/) * (@selym) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951400) * Thanks Cais. The no template setting works perfectly. * I’ll still work on the thumbnail size issue. There must be a setting somewhere that I missed somewhere. * Plugin Contributor [photocrati](https://wordpress.org/support/users/photocrati/) * (@photocrati) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951401) * [@selym](https://wordpress.org/support/users/selym/) – You may need to go under Gallery > Other Options > Thumbnail Options to set the thumbnail dimension and also set fix dimension to Yes. * Then you may need to ensure the NextGEN Basic Thumbnail settings under Gallery > Gallery Settings are also set fix dimensions to Yes … and then regenerate the thumbnails (again?!). * Hopefully all of that inconvenience will help to sort out the issues with the thumbnails you are seeing. * – Cais. * Thread Starter [selym](https://wordpress.org/support/users/selym/) * (@selym) * [11 years, 11 months ago](https://wordpress.org/support/topic/thumbnail-and-display-issues/#post-4951404) * Thanks Cais. Unfortunately both those settings seem to be set appropriately. * I’ll keep messing around, clearing cache, regenerating thumbs, etc. Luckily this only seemed to happen on a group of a half dozen galleries, so worst case I can just manually resize and upload via ftp or something, but hopefully I can figure this thing out. * Thanks again for your suggestions.
