The foogallery shortcode is pretty powerful. There are a few attributes you can add to the shortcode to tweak it slightly from page to page and still use the same gallery.
You only want to show a maximum number of thumbs. Code example to limit the gallery to only show 3 thumbs:
[foogallery id="123" limit="3"]
You only want to start showing thumbs from a particular index. Code example to only show from the 4th thumb onwards:
[foogallery id="123" offset="3"]
You can override which attachments are shown in a FooGallery completely by providing an attachment_ids attribute:
[foogallery id="123" attachment_ids="45,46,49"]
The ids 45,46,49 used above are the attachment id's.
Override Gallery Template
You can override the gallery template:
[foogallery id="123" template="masonry"]
If you want, you do not even need to save a gallery to display one. Simply use the shortcode and provide a gallery template and which attachments must be used:
[foogallery attachment_ids="45,46,49" template="masonry"]
