It creates a thumbnail name like 299x240-images-stories-yourfolder-filename-pic1.jpg. This means a lot of data on your server that isn't used and probably doesn't help the SEO of a website.
My idea is that it would be better to have it create a name that just shows filename-thumb1.jpg.
This plugin looks ok but it gives many troubles. It changes on different browsers and indeed does funny things you don't want it to do.
The support is also crap! They do anwser questions on their forum but only the simple ones. Others are left for dead.
If you design stable company websites don't use this plugin. Maybe when you... Naahhh just look for something better and skip this one!
Positive: I like their rotating banners they are nice!
