bmesser	Posted - Jun 12 2026 : 03:37:35 Hi I have a folder with hundreds of 1024x1024 PNG images in it. I want to remove any identical images in it. I wonder if there's an easy way to compare images in imageen? AI provides me with a method, but I would rather go the easier and quicker route if possible. Bruce

xequte	Posted - Jun 12 2026 : 16:31:45 Hi Bruce So the quickest method is to get a hash of all the images and then find the ones with the same hash: http://www.imageen.com/help/TIEBitmap.GetHash.html Of course, that only gets you 1:1 matches. You might consider ones that are the same but different sizes, or colors. So you might want to scale the images to a standard size (not relevant for the case you mention that are already the same size) or convert to gray scale. Generate the hash for the sub-subsampled images. The other potential issue (again, not in the case you mention below) is JPEG compression differences, so in that case you are better to reduce to a much smaller size and compare that.
