Topic awaiting preservation: Server side Image Resizing

Hope this is the right place to post this.

I'm interested in knowing more about applictaions/scripting that allows you to resize images uploaded to a server.

Basically, I would like to be able to upload a HiRes pic (JPG or TIF) and have the server make me a smaller version (dimension and weight) that can be used on a webpage. The smaller (not quite thumbnail) image should link to the HiRes for download (for print work).

I'm not really needing actual code for this, but rather pro's and con's (does image quality deteriorate much compared to resizing it manually in PS) and what language would be preferred. I think some of you were working on something similar for PSPong.com. (INI, you know something about this, right?)

We are thinking of including such a function in an administration tool for products. We run an all-MS infrastructure (W2K/IIS/SQL2K/ASP/XML)

All tips and opinions are most welcome.
(oh, and to simplify, please keep it on a semi-dummy level. I'm no coder. I'm looking for some info to pass on to my development group )

Now that you mentioned that you're Windows:
http://www.leadtools.com/

They have lots of imaging component that can be used programatically from within any windows application.
I believe that also have ActiveX components which can also be used from your ASP documents.


Yes, I believe there might be loss in the thumbnailing process, Perhaps PS's photo processing engine is better than LeadTools' engine.

Good luck.

The poster has demanded we remove all his contributions, less he takes legal action.
We have done so.
Now Tyberius Prime expects him to start complaining that we removed his 'free speech' since this message will replace all of his posts, past and future.
Don't follow his example - seek real life help first.

IMHO Images resized with GD library don't have very high quality. So, instead of GD I would suggest you to use ImageMagick...

That's next on my list of "new things to learn", now that I found that Dreamhost has it built into the servers, yum! I have a very simple Perl CGI on the OZONE server, something written by my friend drow about 1996 or so, but it's too much beyond my control, I need to write a good thumbnailer at least, and do it myself so I know what's happening. What I'd be interested in doing is using it for building graphical buttons as they are needed and then storing them, that could be fun. (And of course, image archives, need need need!

Your pal, -doc-

Thanks a lot for the information.

We'll see if we get this feature up-and-running after the summer (if everything with our company merge works out )

Doc:
For creating buttons and such you might want to take a look at Dimac's w3Image

Seems to be easier to integrate and create better quality than Macromedia Generator!
(oh, and the enterprise package is at just US$295 (free trial available) compared to MM's US$999 (I think)
