    We have a bought copy of advanced batch converter 3.9

    Can hunt out all images in folders/sub folders then I just let it run - can do many things other than resize....

    I know space is a big deal to most of you techies but you realise that when you compress jpgs you not only mauke them smaller is size but also drastically reduce their quality and make them only useful for geeky things such as websites?

    You think?

    How many of the JPG's on school networks get printed out larger than A3 on high quality photographic paper then?

    Even 1024 images in my opinion are fine for inserting in to office apps and printing off full size on laser printers on rubbish paper....

    I also dispute that it DRASTICALLY reduces their quality - was nt that long ago that digital cameras could only take at 1024 resolution - did see anyone complaining then.....

    I personally don't even think the ART department need to be saving at 3488 x 2616 IMO...

    Ah so it can be automated! Thanks for this - I will investigate this software!

    You realise that 1024px wide is still plenty big enough for most things though, right?

    Todays digital cameras produce absolutely HUGE images that only need to be left that way if they want to be printed on full-page A4 photo-paper and that sort of thing. And even then the original size is probably still not needed.

    Bear in mind that you can get photos off digital cameras that are 3000px wide easily, and then consider that a 1920 px wide image is a decent size for a HD display!

    It's just a script that will search a directory tree for .DOC files which are bigger than a specified size and older than a specified age. Those it finds, it will resave as .DOCX, regaining lots and lots of space :-)

    Call me dim if you want, but how is this script supposed to be run? Is it supposed to be saved as a .bat file or something similar?

    Sounds very useful, if I can understand what to do with it!

    Also, how does it work? Do I need Office 2007 on the computer I run the script on to do the convert, or does it just do it the dirty way and edit the file's properties?

    We use nconvert and a batch file and it seems to work quite well:

    NConvert Software - Free graphic and photo batch converter

    Call the batch file with the required directory, or hard code it into the batch file, and wait

    Code:
    @echo off
    rem if "%1"=="" goto no_files
    
    for /R %1 %%a in (*.jpg) do nconvert.exe -out jpeg -ratio -rflag decr -resize 2048 0 -keepfiledate "%%a"
    goto exit
    
    :no_files
    echo Please call batch file with folder name
    echo e.g resize "s:\"
    pause
    
    :exit
    exit

    @all:

    We use Irfanview here to allow the staff and students to batch resize their photos before uploading them to the shared areas.

    Ohh and of course it's free:
    Download IrfanView and its quick and you can network it, Hmmmmm what else can it do.....................................let me think............................................. .................................................. .................................................. ....Lots and lots of things but its Friday and I have forgotten now.

    But that just applies JPEG compression and removes bits that have been cropped. If somebody takes an image which is 3000px wide and scales it down to fit, the Word document still contains the 3000px version - it doesn't resize it, just drops the quality.

    As above, then...

    Find a teacher has saved 1.75GB of photographs from a recent trip. Twice in the same folder.

    Duplicate deleted, batch resized and folder now only about 300MB

    A teacher had pictures of every single child in the school (~500) and decided to send them to print...in one document...which was 3gb. Print spooler wasn't happy and neither was the rest of our ageing decrepit network.

    a really geeky solution

    for batch resizing (and a host of other things) you might also want to take a look at:

    ImageMagick: Convert, Edit, and Compose Images

    it's free, open Source and will churn through directory's of images happily. Because it's command line it's also scriptable.
