Photo Gallery Links Order - List most recently uploaded first

Hello, this issue has been a thorn in our side for quite some time, with no luck solving it. We desperately need your help!

We need to be able to re-order the photo gallery links that show up in the left navigation of the site (photo gallery block, shown on each page of the site) so that they are listed in order by date uploaded (the link for most recent photo gallery uploaded should show up first). They are currently in alphabetical order, and we have found no way of changing the way they are ordered. Can this be accomplished? Any help would be greatly appreciated!

Thanks,
