I spent 2 days to find this easy solution to translate Gavick GK2 Photoslide using Joomfish content elements.
So before upload the file gk2_photoslide_slides.xml to /administrator/components/com_joomfish/contentelements you have to do the following modification in Gavick’s code:
go to /modules/mod_gk_news_image_1/helper.php and replace:
| 
					 1 2 3 4 5 6 7 8 9 10 11 12  | 
						SELECT `c`.`sectionid` AS `sid`, `i`.`file` AS `file`, `i`.`title` AS `title`, `i`.`text` AS `text`,              `i`.`linktype` AS `linktype`, `i`.`linkvalue` AS `linkvalue`, `i`.`article` AS `article`, `i`.`wordcount` AS `wordcount`, `c`.`title` AS `ctitle`,           `c`.`introtext` AS `introtext`, `c`.`catid` AS `cid`  |
