Warning this is experimental as I'm absolutly not a coder, so use it with caution and don't expect from me any kind of support.
To display multi-language captions do this :
-Open plugin_jw_sigpro.php, backup it up.
-Locate //read labels.txt
-Replace
if (file_exists($mosConfig_absolute_path.$rootfolder.$_images_dir_."/labels.txt") && is_readable ($mosConfig_absolute_path.$rootfolder.$_images_dir_."/labels.txt")) {
$file_handle = fopen($mosConfig_absolute_path.$rootfolder.$_images_dir_."/labels.txt", "r");
With :
if (file_exists($mosConfig_absolute_path.$rootfolder.$_images_dir_."/".strtolower($mosConfig_lang)."_labels.txt") && is_readable ($mosConfig_absolute_path.$rootfolder.$_images_dir_."/".strtolower($mosConfig_lang)."_labels.txt")) {
$file_handle = fopen($mosConfig_absolute_path.$rootfolder.$_images_dir_."/".strtolower($mosConfig_lang)."_labels.txt", "r");
-Create labels textfiles named yourlanguage_labels.txt
ie: french_labels.txt, russian_labels.txt, chinese_labels.txt etc ...
-Put your captions as usual in the text files
