Restarting Image/Gallery Numbering

@topherandrae – If you want to completely remove and start over with NextGEN Gallery it can be a little involved. These steps should help you look at all of the various items NextGEN Gallery touches on that you may have missed:

This process will generally work but we recommend you have a complete fully verified back-up of your site just in case you run into any problems:

Use FTP to remove NextGEN Gallery related folders.
Then use something like https://www.ads-software.com/plugins/wpdbspringclean/ to delete all the ngg tables.
Then use something like https://www.ads-software.com/plugins/database-peek/ to search through the remaining tables for NGG references.
Then use something like https://www.ads-software.com/plugins/edit-any-table/ to delete all of these database entries.

Tables typically involved: wp_ngg_*, wp_options, wp_postmeta, and wp_usermeta

Thanks!
