I didn't think about it at the time, but you could reuse the same resource for your gallery album call.
Lets say the resource that holds your gallery call is 19 and you have the template set to empty or to a special template specifically for your album (DO NOT USE YOUR BASETEMPLATE FOR YOUR WEBSITE).
The gallery call on 19 might look something like:
[[Gallery? &albumRequestVar=`album`]]
And your fancy box call to open your album in a modal window might look something like:
[[sekfancybox?
&type=`document`
&linktext=`Gallery 1`
&link=`[[~19? &album=`1`]]`
]]
[[sekfancybox?
&type=`document`
&linktext=`Gallery 2`
&link=`[[~19? &album=`2`]]`
]]
Note: the "&album=" can be the album id or the actual album name ("&album=`My Gallery 1`").
