You create one great plugin. I tested a lot of other photo plugins but this is a great one. Very little issues. You spent a great deal testing this out and fixing issues that make it easy for people to use and under stand. I rate this 5 start and would recommend this to others. I can support you by giving you a like so other can download it for themselves.
Here is what I love about it:
1) you separated the tables and did not include them in the POST table. I think this is nice and reduces the volume and traffic during loading. Plus increases website speed by keeping them outside the standard WP tables.
2) having all these functions included is a surprise, and makes it pleasure to work with to as it allows me to maintain the website and photos
3) Love the statistics and counts all in the right places - very visible
4) Options and More options - I can change colors without have to play with CSS. Only 500 options stored in settings but it is worth it.
Thank you for the plug-in!
