Built-in PHP library gd does not have ready-to-use function for photo(jpeg) thumbnail generation. Although there are many such examples on the net, they are usually not suitable for effective generating series of thumbnails (for ex. 240x240, 140x140, 80x80). This article provides php function thumbnail_generator and trivial image uploading script, which generates series of thumbnails.

Were going to be creating it in a function, so that we can re-use this wherever we need to. This particular function saves the thumbnail file to a directory on the server, you could actually skip saving the file and just print out the image itself if you would prefer to do that.

0.0(out of 5) Vote:0 PHP class for basic image manipulation
A class providing a set of methods for doing basic transformation to an image like resizing, rotating and flipping. the class is very small (only about 18Kb in size but still heavily documented) and as i said it only covers some basic methods so don't expect miracles. i use it in favour of many other well known scripts that are hard to install, hard to manage, have a thousand files, many megabytes in size and zillions of methods and functions nobody uses. this is how i do it.
