[Plugin: NextGEN Gallery] Can’t generate thumbnails

I’m having the same problem creating thumbnails… I really hope a developer fixes this issue soon.

I’ll add my server info

* Operating System : Linux
    * Server : Apache
    * Memory usage : 11.66 MByte
    * MYSQL Version : 5.0.45-log
    * SQL Mode : Not set
    * PHP Version : 5.2.4
    * PHP Safe Mode : Off
    * PHP Allow URL fopen : On
    * PHP Memory Limit : 128M
    * PHP Max Upload Size : 2M
    * PHP Max Post Size : 8M
    * PHP Max Script Execute Time : 30s
    * PHP Exif support : Yes ( V1.4 )
    * PHP IPTC support : Yes
    * PHP XML support : Yes

Also, I was able to create 2 galleries with thumbnails generated without a problem. now, no luck.

I’m having the same issue with NextGen gallery: it won’t generate thumbnails. When I upload images, it reports the following error:

You do not have the GD Library installed. This class requires the GD library to function properly. visit https://us2.php.net/manual/en/ref.image.php for more information

I installed both WordPress and NextGen gallery (version 1.3.5) for the first time today – I have never used any of it before.

Besides NextGen, I have only the two default plugins installed (Hello Dolly and Akismet) and both are deactivated. So the problem does not appear to be a conflict with another plugin.

My server details are as follows:

* Operating System : Linux
* Server : Apache/2.2.11 (Ubuntu) PHP/5.2.6-3ubuntu4.1 with Suhosin-Patch
* Memory usage : 12.95 MByte
* MYSQL Version : 5.0.75-0ubuntu10.2
* SQL Mode : Not set
* PHP Version : 5.2.6-3ubuntu4.1
* PHP Safe Mode : Off
* PHP Allow URL fopen : On
* PHP Memory Limit : 32M
* PHP Max Upload Size : 2M
* PHP Max Post Size : 8M
* PHP Max Script Execute Time : 30s
* PHP Exif support : Yes ( V1.4 )
* PHP IPTC support : Yes
* PHP XML support : Yes

The images I am trying to upload with NextGen are all small and optimized for the web – they vary in size between 50kB and 120kB. So I doubt whether memory would be an issue.

You can view one of the images here: https://www.martinalees.co.uk/wp-content/uploads/2009/08/rosa-slade565.jpg
I am unsure whether there could be a problem with the metadata on the images.

Please advise. (And please bear in mind that I am a rookie at this, so would really appreciate simple explanations ?? )

Thanks a lot!

I’m having the same issue with NextGen gallery: it won’t generate thumbnails. When I upload images, few 4-5 thumb created others reports the following error:

ID 5017: A failure occurred
[more]
[object XMLHttpRequest]

All images are: 1024×768

I have exactly the same problems:
images of no greater than 40 kB and no thumbnails!!

But then I went to my host and turned off the ‘Safe Mode’ in my profile.
I also changed the permission settings of my gallery map on the server to 777.

I really have little idea of what this all means, but hell, it works!

Good luck to all

First of, thanks Alex for making this great plugin.

I’m having the same issue with NextGen gallery: it won’t generate thumbnails. When I upload images, few 4-5 thumb created others reports the following error:

[object XMLHttpRequest]

I hit this same problem after maybe couple of updates of WP and NextGen-gallery plugin. I started to look this more closely since everthing I did for the php config or WP did not seem to work. Fortunately I have own virtual server and I’m able to look what happens.

The plugin seems to do this in some certain circumstances I don’t know:
1. when uploading images it makes thumbnails on the fly which seems to eat up lot of resources. It makes some thumbnails but when memory fulls it skips the rest.
2. when trying to make thumbnails in Manage Gallery section it totally eats up apaches resources and some cases even gets the server on the knees.

I have 256+256 memory and ordinarily used memory is about 50-60Mb but when I try to make just one thumbnail it eats up hole memory and even the swap file too and server some time crashes and I have to restart it again.

Could there be a bug in that gd.thumbnail.inc.php-file? Something which could get the script looping and thus eating all the memory?

I have LAMP with ubuntu jaunty and latest updates.

If I can be for any help, please let me know.

I was able to fix this problem simply by resizing the dimensions of the files, thanks to @jwcalla’s suggestion. Most of my uploads were generating thumbnails just fine, but for two files I got the [object XMLHttpRequest] error and no thumbnail was generated.

They weren’t the largest I’d tried to upload as far as memory, but they were each about 3000px in their largest dimension. I downsized them to 1000px in their largest dimension and they uploaded and generated thumbnails just fine!

Hope this is helpful to someone.

I am on 1&1 too. What a load of crap. They suggest changing the PHP version to ver 5 and this is supposed to do it.

From an email from 1&1 support:

This is connection with your call earlier.

Create a new .htaccess file or edit an existing one.

Create a “.htaccess” file containing the following line:
AddType x-mapp-php4 .html .htm

Upload this file into into the root of your domain. The changes take
effect immediately. This will effect the directory the .htaccess is
placed in and all the sub-directories underneath it.

How to parse PHP within HTML files

Due to resource limits on our Shared Hosting machines, it is not
possible to allocate more than 20M of memory to PHP, although phpinfo()
may report a higher number. You will be unable to increase the memory
usage limit with a php.ini file.

Hope this information helps.

If you have any further questions please do not hesitate to contact us.

Nope, same error message. I think 1and1 is just too backwards to have a web site using Nextgen on.

Update: I moved the site off of 1and1 and all my problems disappeared.

SOLVED FOR ME!

I had problems too and couldn’t figure out at all. I have two blogs running on the same server and one worked and the other didn’t. I looked at all the stuff here, I deleted plugins, tables, images, etc.

For whatever reason I decided to try editing my galleries in IE and low and behold the thumbnails work again.

I’m sure it has something to do with the junk I have running on Firefox but Chrome didn’t work. I’m not running the latest IE either it’s IE6.

Hope this helps someone.

I had the same problem and I followed the link from crevenco (https://www.visser.com.au/blog/thumbnail-generation-php-memory-limit-nextgen-gallery/). Deleted the 2 slashes and works fine again for me ??
