The real challenge here is to write a image scaling servlet which
renders photoshop quality images!
My suggestion for this part of the problem is to use ImageMagick (Or
GraphicsMagick, if you like) along with Runtime.exec(). I tried to
find something as awesome as ImageMagick but for Java and came up
mostly empty handed. Yes, there is JMagick, but there are several
reasons why you might not want to use it. Some of those reasons are
described here:

Good luck!

Speaking from the peanut gallery, I would prefer the images be
pre-scaled and stored multiple ways in the DMS myself as it speeds up
rendering to the public. Scaling on the fly from a single copy to

Hi Ole,
You seem to be receiving a lot of responses but there's one I would
hope to read but isn't here. I was expecting that the "Magnolia-way"
would be not store multiple instances of the same image, but instead
one instance and be able to deliver multiple instances on request.
In
this case, you would not have to make any changes to the DMS but
instead create a simple servlet that can deliver varying instances.
Unless you REALLY do have a valid reason to store multiple instances
of the same image, I don't see why you should. Since you want to do
the resize on automatically on the upload anyway, why not do it on
the
download. Magnolia is great with caching so you will only have to
resize once just as you would with the upload.
I hope this helps.
Best,
Jackson

I am currently in a very early stage evaluating Magnolia.
I need to import and manage several thousands of product images
with the WCMS/DMS. Typically the images are large jpgs, pngs, gifs
and pdfs. When importing I wish to automatically resize the image
into three sizes: thumbnail, product and large (+ full).
For this I wish to to develop a module/template that:
A) Automatically resizes the images and stores them into the DMS
i.e. under images/products/name-{thumb,small,large,full} upon
upload/import.
B) A template that allows the editor to navigate the DMS by
thumbnails, and insert images with selected size.
Can anybody give me some general pointers for how to do this (the
magnolia-way!)?
Best regards,
Ole Christian
