php - Should I generate each thumbnail dynamically every time it is requested, or store them on image upload? -

this question has reply here:

php image resize on fly vs storing resized images 4 answers

problem - wanted set image-uploading feature in website. wanted show both- original image , little thumbnail of image.

choices - way improve - create separate image (thumbnail) in directory when image uploaded or show smaller version reducing height , width in fixed ratio every time image requested?

how doing currently - later 1 sounds improve me because won't taking much size on disk has resize image 1 time again , again. 1 think better?

this general question web application, no language in specific.

any thought how facebook or google it?

question - question how generate thumbnails , show them on website - creating re-create of original image smaller dimension or generating thumbnail dynamically every time requested.

creating thumbnail on upload improve option. if storage concern convert them on request , cache result in memory store. if requested 1 time again before cache expires, no conversion needed.

storage pretty cheap, not go complexity.

php image web-applications upload thumbnails
