Title: [Plugin: NextGEN Gallery] plugin generates wrong thumbnail size Last modified: August 19, 2016 --- # [Plugin: NextGEN Gallery] plugin generates wrong thumbnail size * Resolved [jimmyjjames](https://wordpress.org/support/users/jimmyjjames/) * (@jimmyjjames) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/) * Hello, * i am using wordpress 3.0 and the NextGEN Gallery 1.5.5 – plugin. for some reasons this plugin generates wrong thumbnail size. for example: in the options i set“ width x height” to “150 x 105” and ckeck the option “ignore image propotions”. * then i upload an image with a dimension of 900×624 and the plugin generates a thumbnail with a dimension of 147×105. but it should be 150×105. * has someone a solution, or is a bugfix comming? * thanx in advance for help, alekz * [http://wordpress.org/extend/plugins/nextgen-gallery/](http://wordpress.org/extend/plugins/nextgen-gallery/) Viewing 15 replies - 1 through 15 (of 20 total) 1 [2](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/page/2/?output_format=md) [→](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/page/2/?output_format=md) * Thread Starter [jimmyjjames](https://wordpress.org/support/users/jimmyjjames/) * (@jimmyjjames) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/#post-1561142) * hi, its me again. * i looked into the source (lib/gd.thumbnail.inc.php). following things i have noticed: * 1. the “resize” function is called, but perhaps “resizeFix” should be called!? 2. param $maxWidth is not set (but should be 150) 3. calcHeight function is called and calculates for the width proportionally the value 147 (instead the new imagesize should be calculated to 150×107 and afterwards be cropped to 150×105) * can someone approve this false behaviour? does someone know, why the param $ maxWidth of the “resize”-function is not set? is someone sure, if the “resize” or “resizeFix” function should be called. * this excellent plug-in is unfortunately useless with this bug. * alekz * Thread Starter [jimmyjjames](https://wordpress.org/support/users/jimmyjjames/) * (@jimmyjjames) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/#post-1561341) * Hi, * so my solution is: * in the file functions.php in line 272 i replace * ``` if ($ngg->options['thumbfix']) { // check for portrait format if ($thumb->currentDimensions['height'] < $thumb->currentDimensions['width']) { // first resize to the wanted width $thumb->resize($ngg->options['thumbwidth'], 0); // get optimal y startpos $ypos = ($thumb->currentDimensions['height'] - $ngg->options['thumbheight']) / 2; $thumb->crop(0, $ypos, $ngg->options['thumbwidth'],$ngg->options['thumbheight']); } else { // first resize to the wanted height $thumb->resize(0, $ngg->options['thumbheight']); // get optimal x startpos $xpos = ($thumb->currentDimensions['width'] - $ngg->options['thumbwidth']) / 2; $thumb->crop($xpos, 0, $ngg->options['thumbwidth'],$ngg->options['thumbheight']); } //this create a thumbnail but keep ratio settings } else { $thumb->resize($ngg->options['thumbwidth'],$ngg->options['thumbheight']); } ``` * with * ``` if ($ngg->options['thumbfix']) { // check for portrait format // first resize to the wanted width $thumb->resize($ngg->options['thumbwidth'], 0); // get optimal y startpos $ypos = ($thumb->currentDimensions['height'] - $ngg->options['thumbheight']) / 2; $thumb->crop(0, $ypos, $ngg->options['thumbwidth'],$ngg->options['thumbheight']); //this create a thumbnail but keep ratio settings } else { $thumb->resize($ngg->options['thumbwidth'],$ngg->options['thumbheight']); } ``` * and it seems to work. * maybe alex rabe could verify this und implement this bugfix into the plugin. * alekz * [swam2222](https://wordpress.org/support/users/swam2222/) * (@swam2222) * [15 years, 10 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/#post-1561542) * Hi Jimmy, * Which file does this replacement code go into?

The last solution wasn’t right. I recognized it just now. But here is the final solution, and for me and the images i have it works. * so again go to the wp-content\plugins\nextgen-gallery\admin\functions.php, line 272 and replace * ``` if ($ngg->options['thumbfix']) { // check for portrait format if ($thumb->currentDimensions['height'] < $thumb->currentDimensions['width']) { // first resize to the wanted width $thumb->resize($ngg->options['thumbwidth'], 0); // get optimal y startpos $ypos = ($thumb->currentDimensions['height'] - $ngg->options['thumbheight']) / 2; $thumb->crop(0, $ypos, $ngg->options['thumbwidth'],$ngg->options['thumbheight']); } else { // first resize to the wanted height $thumb->resize(0, $ngg->options['thumbheight']); // get optimal x startpos $xpos = ($thumb->currentDimensions['width'] - $ngg->options['thumbwidth']) / 2; $thumb->crop($xpos, 0, $ngg->options['thumbwidth'],$ngg->options['thumbheight']); } //this create a thumbnail but keep ratio settings } else { $thumb->resize($ngg->options['thumbwidth'],$ngg->options['thumbheight']); } ``` * with * ``` if ($ngg->options['thumbfix']) { // check for portrait format $wratio = $ngg->options['thumbwidth'] / $thumb->currentDimensions['width']; $hratio = $ngg->options['thumbheight'] / $thumb->currentDimensions['height']; if ($wratio > $hratio) { // first resize to the wanted width $thumb->resize($ngg->options['thumbwidth'], 0); // get optimal y startpos $ypos = ($thumb->currentDimensions['height'] - $ngg->options['thumbheight']) / 2; $thumb->crop(0, $ypos, $ngg->options['thumbwidth'],$ngg->options['thumbheight']); } else { // first resize to the wanted height $thumb->resize(0, $ngg->options['thumbheight']); // get optimal x startpos $xpos = ($thumb->currentDimensions['width'] - $ngg->options['thumbwidth']) / 2; $thumb->crop($xpos, 0, $ngg->options['thumbwidth'],$ngg->options['thumbheight']); } //this create a thumbnail but keep ratio settings } else { $thumb->resize($ngg->options['thumbwidth'],$ngg->options['thumbheight']); } ``` * i hope it works for you too, and it would be nice if this bugfix would be implemented in the original plugin, so we dont have to reimplement it everytime a new version of the plug in comes out. * cu, jimmy aka alekz * [srichand](https://wordpress.org/support/users/srichand/) * (@srichand) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/#post-1561565) * Hi, * Thanks for ur valuable posts…… keep on the good work * [srichand](https://wordpress.org/support/users/srichand/) * (@srichand) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/#post-1561566) * hi, * why lightbox effect is not working for me……??? any suggestions!!!!!!!! * [thedrewseum](https://wordpress.org/support/users/thedrewseum/) * (@thedrewseum) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-plugin-generates-wrong-thumbnail-size/#post-1561567) * Unfortunately this fix didn’t work for me :/ Photos with a size ratio that is slightly ‘off’ still generate smaller thumbnails.
