ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. Downloadable distributions are available for Mac OS, Mac OS X and Linux.
It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw". It supports "stacks", a series of images that share a single window. It is multithreaded, so time-consuming

What's New
Version 1.46o:
- Set the stroke width to 0 in the Edit>Selection>Properties, Image>Overlay>Overlay Options and ROI ManagerProperties dialogs to have selections drawn using a width of one pixel regardless of the image magnification.
- Fixed a bug that could cause selections being moved to not be displayed correctly when the "Use ROI names as labels" option in the ROI Manager was enabled.
- Fixed a bug that caused Analyze>Plot Profile to fail with line selections with widths less than 1.0.
- Thanks to Franklin Shaffer, fixed a bug that sometimes a caused a stack overflow error when importing large image sequences.
- Thanks to Tiago Ferreira, fixed a 1.46n regression that caused overlay items to be removed when toggling the ROI Manager "Show All" checkbox.

ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. Downloadable distributions are available for Mac OS, Mac OS X and Linux.
It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw". It supports "stacks", a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations.
It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering.
It does geometric transformations such as scaling, rotation and flips. Image can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. The program supports any number of windows (images) simultaneously, limited only by available memory.
Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available.
ImageJ was designed with an open architecture that provides extensibility via Java plugins. Custom acquisition, analysis and processing plugins can be developed using ImageJ's built in editor and Java compiler. User-written plugins make it possible to solve almost any image processing or analysis problem.
ImageJ is being developed on Mac OS X using its built in editor and Java compiler, plus the BBEdit editor and the Ant build tool. The source code is freely available. The author, Wayne Rasband, is at the Research Services Branch, National Institute of Mental Health, Bethesda, Maryland, USA.

from the scientist POV imagej allows us to handle, process and analyse microscope data without the need for prohibitably expensive and sometimes unstable software.
for the non-scientist it can be used for all your image needs including scripting for batch processing.

Then when opening a JPEG of aprox. 2500x1900 it threw an out of memory error, which is an absolute joke on a 768MB system that had 160MB free at the time. Considering Preview.app opened the same image flawlessly, what gives?
I would give it thumbs down. Maybe wait until they do a Cocoa/Java port? Who knows. It just doesn't feel very polished at this point.

As for the out of memory problem, you need to increase the heap size of the Java VM in order to be able to open large files. There is a setting in ImageJ for this.

Still ImageJ might have its uses (primarilly if you are operating on a cross plaform basis). Either provide control and manipulation of 16-bit level data in either TIFF or DICOM files. Something GIMP can NOT do.

Don't let a simplistic "X is better" deter you if ImageJ looks useful for your purposes. This ain't perfect (I don't see a bugfix for a way that I crashed my version and some Mac-isms don't work right) but it has a very short learning curve to be very useful.
