Title: [Plugin: NextGEN Gallery] Slideshow problem Last modified: August 19, 2016 --- # [Plugin: NextGEN Gallery] Slideshow problem * [Mike Werewolf](https://wordpress.org/support/users/mike-werewolf/) * (@mike-werewolf) * [15 years, 4 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-slideshow-problem-2/) * Hi, * I’ve installed Nextgen-gallery (1.7.2) with Image Rotator (3.17) for the slideshow( on WordPress 3.0.4). The galleries are well shown on my pages. But if I try to launch the slideshow, I only have a black square with the loading icon, endlessly loading, without showing any picture. * But this doesn’t happen every time ! Sometimes, the slideshow works great, but most of the time, it doesn’t load. * I’ve the problem on 2 websites, with 2 different themes : [http://leblogdetywen.free.fr](http://leblogdetywen.free.fr) [http://leblogdekylian.free.fr](http://leblogdekylian.free.fr) * Some other infos : * The same thing happens with the NextGen Slideshow Widget,* I’ve installed exactly the same websites on my computer (except for wp-config, of course) with EasyPhp (5.2.10) : the Image Rotator slideshow runs without any problem. * On Firefox, when the slideshow isn’t loading, if I press [Ctrl]+[F5], the slideshow will correctly show up (but only once ; if I load a new page, the slideshow won’t load again) * On IE8, same thing occurs if I delete the Temporary Internet Files and then reload the page : the slideshow appears (but once again, if a load another page, the slideshow won’t work). * I’ve also tried to activate the Piclens/CoolIris slideshow, but it’s worse : the slideshow never works (it seems to fail finding the pictures), even on EasyPhp. * I’ve tried to place Image Rotator in wp-content/uploads, in wp-content/uploads/ imagerotator, and in wp-content/plugins/nextgen-gallery, (and update the path to Image Rotator in NGG Options) but nothing change. * Other Installed Extensions : * Lightwindow 2.0 for Images (tried to deactivate, no change) * Thanks for your help. * Mike.

Try to add this code just before you close your head tag: * `` * Thread Starter [Mike Werewolf](https://wordpress.org/support/users/mike-werewolf/) * (@mike-werewolf) * [15 years, 4 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-slideshow-problem-2/#post-1861044) * Hi, * I’ve checked the two themes I use : they both already have this code just before the closing head tag, in header.php. * Thanks anyway. * [juhao](https://wordpress.org/support/users/juhao/) * (@juhao) * [15 years, 4 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-slideshow-problem-2/#post-1861051) * Hello, * I wonder if this observation of mine could be of help. Background: I updated both the WP and NextGEN to the newest versions today (3.0.4 and 1.7.2), both the automatic way and all appears to work fine. Now a couple of slide shows are behaving interestingly: the shows scroll through the pictures as earlier, but after the last picture there is a “broken picture symbol” (or a gray box or a alt/title text, depending on which browser I’m testing with. The box being gray is due to my theme, I strongly guess). When I click on the broken picture to look for it’s properties (to see the path etc.), I see this info about the picture:…. com/en/undefined , this _undefined_ might help to resolve the question above? Could it be a JQuery topic? * The site is under construction, but You may take a look at what I’m trying to describe here: [http://www.valkonenpohjonen.com/en](http://www.valkonenpohjonen.com/en)- > further: the pictures under these two titles “A – bigger …” and “B – the smaller…” * Another thing: both FireFox and IE hung up for a while when I’m updating pages etc. This is a new feature after updating. Unfortunately I can’t say if this happened after updating WP or NextGEN. I didn’t pay attention enough, sorry. * BTW: when i look at the site in Opera (version 11), the pictures are stretched beyond recognition. All pictures. This happened already earlier, before updating. Haven’t really looked into this Opera-problem yet. * [juhao](https://wordpress.org/support/users/juhao/) * (@juhao) * [15 years, 4 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-slideshow-problem-2/#post-1861052) * A question to RiodaV: can this wp_head-function be moved down on the template source code? Can I brake something? I have it now as not-the-last-line before closing of the head tag. I use Atahualpa 3.5.3. and am not planning to update the theme quite yet since there seems to be some open topics with the newest version. * [RiodaV](https://wordpress.org/support/users/riodav/) * (@riodav) * [15 years, 4 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-slideshow-problem-2/#post-1861053) * wp_head() is used by well coded wordpress plugins to recognize the end of the head tag, in order to add elements such as styles, script, etc. * You can move it and there aren’t serious risk because you can always move where it was before. For example I’ve placed wp-head not before the head tag but before some scripts and styles to fix plugins conflict. In the end it’s all up to your specify needs.
