Title: nextgen thumbnails problem Last modified: May 2, 2024 --- # nextgen thumbnails problem * Resolved [jasperazzi](https://wordpress.org/support/users/jasperazzi/) * (@jasperazzi) * [2 years ago](https://wordpress.org/support/topic/nextgen-thumbnails-problem/) * Hi, * I’ve just installed your plugin. It didn’t display any photos on the map. After switchting for firefox to safari I’ve discovered in the JS console an error for trying to get a thumbnail image. E.g. like this: [https://overlandjournal.nl/wp-content/gallery/test2/thumbs/thumbs_england-london-bridge.jpg](https://overlandjournal.nl/wp-content/gallery/test2/thumbs/thumbs_england-london-bridge.jpg) * This page give’s a 404.In nextgen the thumbail options are default, and I’ve selected the test photo in the gallery and re-created a thumbnail image but alas. * When configuring your plugin with [ thumbs=2], the pins, the map works as it should. * [https://overlandjournal.nl/test/](https://overlandjournal.nl/test/) * I’ve added 2 maps to this URL; let me know if I can find somehting more out on where the failure comes from. Is this an update in nextgen gallery, or a setting over there? Or something in your plugin? Anyway, if you could kindly look into this that would be fantastic. * br,Jasper Viewing 5 replies - 1 through 5 (of 5 total) * Thread Starter [jasperazzi](https://wordpress.org/support/users/jasperazzi/) * (@jasperazzi) * [2 years ago](https://wordpress.org/support/topic/nextgen-thumbnails-problem/#post-17742304) * Hi [@pablo2](https://wordpress.org/support/users/pablo2/) .. could you kindly look into this issue or send me in the right direction? * At the moment the plugin can’t be used with thumbnails like stated above. * Plugin Author [Pawel](https://wordpress.org/support/users/pablo2/) * (@pablo2) * [2 years ago](https://wordpress.org/support/topic/nextgen-thumbnails-problem/#post-17742555) * Hi Jasper, * I’m not sure what is causing this but I will try to help. There are online some web pages which you can check. Like this one: [How to Fix ‘Failed To Load Resource’ Error in WordPress (wpbeginner.com)](https://www.wpbeginner.com/wp-tutorials/how-to-fix-failed-to-load-resource-error-in-wordpress/) * I suggest first checking if the thumb files physically exist at the location pointed in the in the console error using any FTP clinet or one in your cPanel. i.e. your_web_page_directory/wp-content/gallery/test2/thumbs/thumbs_IMG_4438- scaled.jpg * If they are there it would mean a permission issue most likely. * You can try to disable all other plugins. Maybe one of them is affecting this. * If they are not there this would be strange. Hmm. I suppose you can see thumbnails on the NextGen Manage Galleries page? You can right-click on one of the thumbnails and open it in a new window to compare an address to this thumbnail with an address in the error. My pluggin suppose to aquire the same address. * Please let me know what you will find out. * Good luck * Pawel * Thread Starter [jasperazzi](https://wordpress.org/support/users/jasperazzi/) * (@jasperazzi) * [2 years ago](https://wordpress.org/support/topic/nextgen-thumbnails-problem/#post-17744317) * Hi Pawel, * Thanks for looking into this for me and your extensive reply. I did some digging: * The files are present in wp-content/gallery/test2/thumbs/ -rw-r–r– 1 www-data www-data 15867 May 2 22:51 thumbs-IMG_4438-scaled.jpgAnd are right owner + world readable. * The source for the gallery2 thumbnail image is: [https://overlandjournal.nl/wp-content/gallery/test2/thumbs/thumbs-IMG_4438-scaled.jpg](https://overlandjournal.nl/wp-content/gallery/test2/thumbs/thumbs-IMG_4438-scaled.jpg) and that’s working. * But when loading the plugin/map Safari console states the 404 for : [https://overlandjournal.nl/wp-content/gallery/test2/thumbs/thumbs_IMG_4438-scaled.jpg](https://overlandjournal.nl/wp-content/gallery/test2/thumbs/thumbs_IMG_4438-scaled.jpg) * See the difference in underscore / hyphen between ‘thumbs-filename.jpg’ or ‘thumbs_filename. jpg’. How does your plugin gets this URL? I’m at holiday with a laptop so a bit limited in checking out the source and debugging 🙂 * Kind regards, Jasper * Plugin Author [Pawel](https://wordpress.org/support/users/pablo2/) * (@pablo2) * [2 years ago](https://wordpress.org/support/topic/nextgen-thumbnails-problem/#post-17745789) * Hi Jasper, * Well-spotted difference and I found the reason and the solution. * In one of the NextGEN gallery files I found this comment: * _// This next bit is annoying but necessary for legacy reasons. NextGEN until 3.19 stored thumbnails_ _with a filename of “thumbs\_(whatever.jpg)” which Google indexes as “thumbswhatever.jpg” which is not good for SEO. From 3.19 on the default setting is “thumbs-” but we must account for legacy_ _sites._ * Fortunetly, they added an option in the settings to change it back to _. * Please go to _NextGEN Gallery > Other Options > MISCELLANEOUS > Use dashes instead of underscores when generating new image files >_ Change to **NO**. * Please read the info when you hover above the option text. They are saying to use “Clear image cache” option after changing. Maybe thumbs will need to be recreated. * I will add a fix also to my plugin to recognise which one to use but I don’t know how long it will take me. Maybe I will find some time over the weekend but maybe 2-3 weeks longer. When I will finish my plugin should choose a correct symbol regardless of this setting. * Best reagrds, * Pawel * Thread Starter [jasperazzi](https://wordpress.org/support/users/jasperazzi/) * (@jasperazzi) * [2 years ago](https://wordpress.org/support/topic/nextgen-thumbnails-problem/#post-17752128) * Hi Pawel, * Many thanks! It’s working with the legacy setting. I’ll upgrade when you have patched it. * Thanks again!
