ImageDiff is a pixel by pixel image comparison tool. ImageDiff allows you to compare two images side by side, and see a difference mask showing you the exact pixels that have changed. Features include: Compare images of different formats, including JPG, GIF, BMP, and TIF, PNG. Compare images of different proportions and imageDiff will scale and calculate the difference automatically. Apply colored filters to see the degree of change between the images. Metrics indicating percent of pixel change and percent of color change. Adjust tolerance to eliminate compression noise and artifacts. Overlay the original unchanged pixels to see exactly where change occurred. Version 1.0.1 may include unspecified updates, enhancements, and bug fixes.
Won't run, adds "anti-virus" programs I don't want.
Pros
-It's free? At least I didn't pay for this garbage.
Cons
-Adds unwanted software, even if you custom install and uncheck all the boxes
-Program won't run. Instead, loops the installation procedure.
Summary
Stay far away. I'm going to look for an alternative.

Cannot think of any.
Cons
Failed to install and required installation of some other program I don't trust.
Summary
Good Quick compare tool for images
Todd260
Pros
Easy to see the differences. Many modes to help change contrast as needed.
Cons
no quick way to compare like off of the right click menu. Other comparing tools have this functionality and it make file selection much easier.
Summary
Good tool still kind of slow to use. I would give it 4 stars if it gets a right click menu option.
It's Ok, does the trick.

Pros
Heat map displays differences well. Easy to spot where it's different.<p>It's free :)
Cons
- no drag and drop of files onto application<p>- no "send to.." shell integration<p>It really needs these as browsing to files all the time is annoying.
Summary
Limited, but efficient

Pros
Useful for determining exactly what pixels have changed, but not much else. Interface is simple and intuitive. There is a button to load the left picture and one for the right. There is a slider to adjust the threshold, and a button to compare. The result is presented in a 3rd, larger window.
Cons
There are 4 "modes" to compare, 3 of which only seem to change the color. Would like the slider to be interactive, rather than adjust, then click to see the result.
Summary
Free no frills pixel compare solution
slansing
Pros
It's free (a little ad is displayed at the bottom)
<p>It overlays the pictures and shows the difference
<p>It has an adjustable threshold meter and reports what % pixels have changed.
Cons
It has an installer (when it probably could be packaged into a single exe)
<p>It only does the things I mentioned - but hey ... it's free - I didn't expect anything more.

not worth downloading

Pros
Free (but...)
Cons
This has potential, but is poorly developed. The version here has a memory leak and locks up after a short while. The interface is also somewhat clumsy. There is a slightly better version on the company website (that does not lock up). IMHO an organization that wants to portray itself as a professional software firm should put out better stuff than this.
