Ask daveb!: How do I resize large groups of photos?

Wednesday, January 4th, 2006

Jesus bleedin’ nuts! I’ve got reader-submitted questions coming out of my ears. I’ve had to backlog a few, so don’t worry, I’ll get to you. This next question is right up my alley.

Q:

Here’s a question that may actually be within your realm of experience; I have a bunch of images I’d like to resize, smaller, for uploading. Is there an easy way to do this to many images at once, say, in photoshop? Or perhaps another, preferably free application I could get my grubby little hands on? Thank you, oh wise and gratuitous davebgimp!

A: Easy as your mom! I’m going to answer this a bit backwards by first addressing the issue of software. Yes, you can do this in PhotoShop or the slightly neutered and cheaper PhotoShop Elements. PhotoShop’s a great program. I use it daily at work, but it costs an ass-load so most people end up pimping out Grandma to buy it or they steal it. Personally, I think that for most users, especially those who are working primarily in an RGB (red, green and blue) color space — web publishing for example, it’s not necessary.

Another option is to take the free route. There’s a few more steps involved but it costs several hundred dollars less… actually it costs nothing. There’s an Open Source, free image editing alternative called GIMP, which stands for GNU Image Manipulation Program. It’s available cross platform, so is accessible to anyone. I use it at home on Linux and having used PhotoShop professionally and otherwise for the past six or so years, I find it meets and exceeds all my home-use needs. Experienced PhotoShop users making the switch might get a bit annoyed at first, as I did, at the learning curve involved. I chalk it up to the fact of using one program exclusively for so long and getting used to the tricks and shortcuts and then trying out a new application with different tools, names and ways to get things done. But once I got past this (it was a quick transition), I found myself impressed and not missing much. If you’re new to either program, I highly doubt you will share this temporary and arguably unnecessary frustration.

The GIMP does have limitations in it’s lack of CMYK (Cyan, Magenta, Yellow and Black - a color space normally used with professional printing and presses) support and a rather huge learning curve if you want to install some plug-ins and know nothing about compiling from source code. Unless, you’re designing for print on a professional scale, you won’t be missing the CMYK support though. I have heard that there’s a CMYK plug-in available, but as of the latest version, the color space is not natively supported. No biggie for me or you other average home users. As far as having to compile programs for GIMP plug-ins, if you’re using Linux, you either know how to do this, or could stand to learn for your own good.

You should at least check out the GIMP. Since it’s free, you don’t have the problem of shelling out for a program that updated with a new version almost yearly (which means more $$$ or more pirating if you want to keep up with the latest). GIMP will always be free of charge and there’s plenty of documentation, tutorials and communities to help you get the hang of it, or you can always ask daveb.

Now, on to the first half of your question. I’ll explain how to do batch resizing with both PhotoShop and the the no-cost method. Let’s start with PhotoShop.
