quick and dirty script that detects duplicate image files and generates an html report with a list of duplicates.

I built this for my wife who wanted a way to easily identify duplicate images on our growing collection of pictures. Plus, it was an excuse to write something new in Go. =)

Running this utility on a directory of images will do the following:

• Recursively scan the directory looking for image files (currently only jpegs)
• Add each image file path to a map of slices with the filesize as the key looking for potential duplicates
• MD5 hash all files that have the same filesize looking for true duplicates
• Generate thumbnails of all found duplicates
• Generate an HTML report allowing for filtering on particular folder
• Other than scanning for files and generating a report this command line app DOES NOT attempt to delete, rename or move files around. It is purely designed to yield a report for further analysis currently.

• Enhance to run in parallell with Go's awesome goroutine/channels
• Enhance to work on additional image types or even any file type
• Modify to use Go's template library (should have started with this, but was lazy)
• Enhance with command line options as necessary
• Add unit-tests

//To install
go get github.com/deckarep/gotdoops

//Then open up a command line and run the following:
go run gotdoops.go [folder/with/images]
