Title: [Plugin: NextGEN Gallery] Edit thumbnail problem Last modified: August 20, 2016 --- # [Plugin: NextGEN Gallery] Edit thumbnail problem * [ckworld](https://wordpress.org/support/users/ckworld/) * (@ckworld) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-edit-thumbnail-problem/) * I am having a problem with the “edit thumb” function of NextGEN gallery. I found many posts in these forums of people experiencing the same problem (the full size image on the left was not loading, and the cropping tool did not present itself). None of the potential solutions I saw in any of the threads had any positive effect on my situation. * I am using Next Gen version 1.8.3 * Anyone have an idea how to solve this ?? * [http://wordpress.org/extend/plugins/nextgen-gallery/](http://wordpress.org/extend/plugins/nextgen-gallery/) Viewing 14 replies - 1 through 14 (of 14 total) * [aredorange](https://wordpress.org/support/users/aredorange/) * (@aredorange) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-edit-thumbnail-problem/#post-2393932) * same problem here with Thumbnails – cannot see them… I am using the latest version of NextGEN Gallery and the latest version of Atahualpa theme, as well as latest version of WordPress… can someone help, please? * [Pioneer Web Design](https://wordpress.org/support/users/swansonphotos/) * (@swansonphotos) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-edit-thumbnail-problem/#post-2393936) * I ran into this issue and it was actually multi-fold. * Issue 1) Shared host script timeout was 30 seconds, NextGen scripts may take longer than this when working with large or many images (it’s a ‘the server is busy thing’) and well, NextGen does not realize this and some things like thumbnail creation are not performed or maybe the exif data was not extracted…try to fix this by deleting the gallery at issue and only doing one pic or a few at a time. When editing, save after each change, making many edits then saving can also cause this…save small bits… * Issue 2) File size. Try to optimize the images for web. Also review the settings in NextGen options for thumbnails. * Issue 3) Browser..try a different browser. Also, refresh that page after you have made any site changes (not in admin mode, but when you are looking at your site and not logged in). * Tip: Note: This applies to the NextGen functions that use the static thumbs only,** some functions create them on the fly**_) The thumbnails can be created by NextGen, but they do not have to be…they are the same name as the original images with a thumb\_ appended and re-sized smaller…if you continue to have issues these thumbs can be manually created and then overwritten to the thumb folder for the gallery using ftp. Once you have a gallery with images in it, use your ftp client to review the folders for that gallery. Download the gallery folder images, copy and re-size, rename accordingly, upload ‘thumbs’ to the thumbs folder within the gallery folder (overwrite)…as you used the original images, the thumbs should also include the exif info like caption, title and description (which you used a photo application to include prior to actually uploading the original files as then those fields are auto-filled in in NextGen, yes?) If this is ALL done correctly, all will be well when you add the shortcode. * Thread Starter [ckworld](https://wordpress.org/support/users/ckworld/) * (@ckworld) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-edit-thumbnail-problem/#post-2393937) * I am not sure if we are talking about the same problem. * Creating the thumbnails or recreating them works perfectly. **I can see the thumbnails** in the gallery and on the page in the website. * _The editing of an individual thumbnail in the gallery is the problem. ** There is ar as far as I know no server side issue, no memory issues. The file size is not big, 300 Kb max, usual 50-100 Kb. * [Pioneer Web Design](https://wordpress.org/support/users/swansonphotos/) * (@swansonphotos) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-edit-thumbnail-problem/#post-2393938) * We are talking about the same problem.

It is just 1 and small image. I cannot see why it should be in this case a time out issue. * Issue 2) File size. The file sizes are small, usual 50-100 K max * Issue 3) Browser..try a different browser. Same problem in Firefox, Chrome, Safari and IE. * Refreshing logged in or out makes no difference * Thank you for trying to help, but this is not the answer. * [Pioneer Web Design](https://wordpress.org/support/users/swansonphotos/) * (@swansonphotos) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-edit-thumbnail-problem/#post-2393942) * Did you try to manually create the thumbs and/or replace the gallery?

I had the same result as you, same issue with editing some thumbnails (and found it was the ones with special characters). * I went through each, renamed them 1 though some # .jpg, and removed the title and description exif data and recreated the gallery. * Once I did that the issue went away. * Yes, I had to manually enter the title, desc. in the gallery manage area, but it fixed the problem. * [Pioneer Web Design](https://wordpress.org/support/users/swansonphotos/) * (@swansonphotos) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-edit-thumbnail-problem/#post-2393970) * Here is the [FAQ for a plugin that works with NextGen](http://wordpress.org/extend/plugins/nextgen-gallery-custom-fields/faq/).
