Thanks,
Well the point 2 i will fix that, for the 1, i will explain why is hard to try to see alots image, the plugin search all image in your database, for each one, the plugin will try to find the image in one post, so if each image have 5 size (orignal, large…) that will be for one post and one image 5 search.
Ex
If you have a blog after 1 year and you made one post every 3 day, and you put 3 image in every post, you will have some like 100 post and 300 image witch each one of then will have 5 size.
You would want to see all this image in the main page, so the plugin have to do 300*5*(100/2) querys to the database if one of then takes 0.01s the time total will be 750s so 12m. (for only 300 image and 100 post!!)
If you want to make your own math with your own values the the ecuation will be
Time=nI*5*(nP/2)*T => nI: number image in your wordpress site, 5 number of size for each image, nP number of post and nP/2 is average for find one image in the same post position. T is the time in secunds that your database take to make a query (i put 0.01 but can be more or less, depends of your server configuration)
I will try to find a new logic for do the search better, but is hard to find.
I will put this explanation in the main page of the plugin 🙂
