Easiest Way to Downsize 1080p images

I downloaded some HD 1080p images to use as a backdrop for XBMC. However, the files take too long to appear on screen.


What's the easiest way for me to downsize them to a size that appears quicker and what size should I pick? Is there a script I can use or a way of doing them all as a batch. I have all the images in one directory.

IrfanView has a batch mode.

You could also use a command line tool like imagemagik.

Do you have dds enabled? It should cache them.

I created a little program like this ages ago to do exactly the same thing. Give it a source folder, a destination folder and set the width, height and image format you want and hit start. It'll automatically create the images for you in the destination folder.

Grab it from here: http://dl.dropbox.com/u/3687220/AutoResizer.zip

Grab Irfanview and install.

Open irfanview, and select File
Scroll Down to Batch Conversion/Rename
You may want to use Batch Conversion Rename Result Files or change the Output directory
Tick the box "Use Advanced Options (for bulk resize)" in Batch Conversion Settings
Click Advanced Button next to it
Click Resize
Input desired size (such as 1280 720 etc.)
Tick "Use Resample"
(Clicking Save will save .ini file for future use) , click OK
(Back in the original Batch Conversion dialog box)
Move to chosen directory (LOOK IN) and click Add All
make sure Output directory is different (or it will overwrite files, not good on the first go - keep originals until happy with results!)
