in reply to Upload with image resizing by Image::Magick

The way I've done it in the past:

- receive the file upload using CGI.pm or Apache::Whatever

- save it (making sure the filename is untainted)

- ask image magick if the file is an image of one of the types you're willing to accept (delete it if not)

- run image magick's resizing thingy as a system call. let the web server return a page to the user, while leaving IM to get on with things (because it can take a while for big files).

Also, be aware that image magick resizing can use a lot of memory for large files. so you might want to restrict the size of the file upload.

hth!
