Hi,
Could someone please point to to a tutorial / code for dynamically resizing
images on upload, THEN saving to disk on the webserver.
I need users to be able to upload images to my server, but they will not be
aware of optimising graphics for the web, if someone uploads a 300k 640x480
jpeg for example, i need to be able to shrink it down to a - say 400x300 65k
file BEFORE saving to my webserver.
I have been looking on the web and have found plenty of code for resizing
images and dynamically outputting an optimised images from heavy images that
reside on the server, but i need to shirnk it after getting it from the user
as an input stream before saving it to disk to save disk space.

in summary:
user uploads 600k jpeg via file field in web form
code then shrinks this down (may shrink physically or reduce quality or
both)
saves to disk a 65 k jpeg to disk on the webserver.

(note that i'm not interested in the GetThumbNailImage method for jpegs as
this produces too small an image)

I'm sure there is a tutorial out there for this, or if someone has code to
post here to this that would be fantastic

Thanks for any help.

Tim..
 
Thanks for your reply, but that doesn't really help... The thumbnails are
too small.
I have done a workaround where i am saving the uploaded image to disk first,
then resizing it and saving a smaller/optimised version.
still interested if anyone has seen a tutorial to do this in one step, or if
someone has code can they post it or email me
Thanks

Tim
