simple image gallery

hello people
installed ot corp mx full on a client's website (joomla template with what was in the package)
I'm trying to use simple image gallery in ot corp mx
put the correct path and code (images/sampledata/2013/caminhoes/extra {gallery} {/ gallery}

I have the following error:
JFolder :: files: Path is not a folder. Path: / home/storage/2/6a/7d/metroshacman1/public_html/images/images/sampledata/2013/caminhoes/extra
There was a problem rendering your image gallery. Please make sure the que folder you are using in the Simple Image Gallery plugin tags exists and contains valid image files. The plugin Could not locate the folder: images/images/sampledata/2013/caminhoes/extra

what should I do to work?
can show me some other similar preferably free plugin that works?

thank you

Hello,

You are doing wrong config for simple gallery plugin.

1. You just need fillout Image folder path: images/images/sampledata/2013/caminhoes/

2. In k2 or Joomla item you should fillout {gallery}extra{/ gallery}

Best Regards
