For those like me who need to work with a lot of images to upload onto blogs or their websites, a batch photo editor is a real boon. There are multiple options available and depending on your appetite for geeky-ness. The one that I use and find the easiest to use is Phatch (Photo Batch). This piece of software is available for Linux, Mac and Windows, though it is originally a Linux package. I currently use Linux Mint which is based on Ubuntu 8.10.
Installing Phatch in ubuntu through apt is easy and it takes care of installing all required python dependencies too which are required for Phatch to run. You can also download Python, wxPython and Python Imaging Library (PIL) from their respective sources and Phatch separately. An all in one deb file is also available here.
The interface is simple and clean. All you really need to do is choose a series of actions that you would like to carry out on the images. The “save” action comes at the end and the user is prompted to add it too. Each action has its own set of settings that you can play around with and set for that particular action. Once you have chosen the set of actions, you can save this actions list to be used later. So if you need to have different settings for different websites, you can save multiple action lists.
The actions that you can perform are: Resize, Rotate, Rounded Corners, Shadows, Watermark, Colour Mode, DPI Change, Rename, Save in various formats etc. And these are just the popular ones. There are many more that can reduce the amount of time you spend working on images to minutes instead of hours or days.
Now all that needs to be done is point Phatch to the source folder. You can provide either a folder from which all the images need to be processed or you can choose files separately.
While saving the files you can specify things like the quality, the format and the name with built in templates. I have never found it easier to batch process files.
If you are like me and use magazine style themes for wordpress blogs, Phatch is a life saver. The main feature of these themes is the extensive use of images, and they generally require 2 or 3 versions of an image to make the page look appealing. All you need to do is save your settings for different types of images in different action lists and use them when required.
