It's great to have descriptions for galleries, but having the same description used by all affiliates for a given sponsor FHG is NOT GOOD when it comes to SE issues.
DUPLICATE CONTENT PENALTIES (by search engines) are REAL!
Especially in light of recent algo changes by one of the biggest SEs, you should be using *unique* titles and descriptions for your links or you run the risk of having your own site 'sandboxed' by SEs and your sponsor may lose SE prominence as well due to what would appear (to SEs) as 'site scraping'.
If you don't care about SE traffic, disregard this.
But, if you know that SE traffic converts much better than other types and does not cost as much to build, why shoot yourself in the foot?
Either write your own gallery titles or descriptions, or use a tool which does it legitimately for you:
