Ahh. Should have read the whole lot. Thanks
If you enable ‘back up images’ in the Nextgen options you can download the hires backed-up version rather than the web res version displayed on the site.
Change the hires file path to
$hiRes = $initialPath . "gallery/" . $loResImgDir ."/" . $loResImgName."_backup";
Anyone know how to strip the _backup off the name before zipping?
I’ve had the error too with a different plugin. Only on the MAMP local site not on a live site so I changed the PHP version to 5.2.17 in the MAMP preferences.
The plugin works fine now.
