As I understand it the current way WP Photo Album Plus generates thumbnail images is to do it on demand, thumbnails are not generated just once and stored permanently as separate images files to be reused.
So if I insert a thumbnail image into a post every time the page loads (leaving aside anything like browser caching) a new thumbnail needs to be generated. Obviously this has a negative impact on page loading times especially if you have a page with a lot of thumbnails, as I do. Similarly the thumbnail image in the sidebar created by the photo of the day widget generates it's thumbnail when the page is loaded adding to page load times.
I used to use the Gallery 2 package for my photo gallery and it generated separate thumbnail images (using sizes set by the user) at the time of image import which it stored permanently. This meant that page load times were faster as no thumbnail image generation was being done as part of the page loading process just the loading or pre-rendered images.
Could such a feature be added to WP Photo Album Plus?
