Hairball

I realize this thread is over a decade old but it came up in a Google search since I actually have this exact issue. Here's the interesting insight that I can give to my instance. I attend a lot of pop culture cons and I scan in images I have signed at these shows so I know what I have and so I don't make the mistake of purchasing duplicate images. For the longest time, I've used Epson scanners to scan, resize, crop and save as .jpg files. I always scan as .tif since it provides a better original to work from. I've used Paint.net for eons as part of my workflow and never had any issues. I recently purchased an HP product that can scan 11x17 images and this is when the error began. Once I open the .tif file and clean it up, I know it's going to fail as soon as I change the file extension to .jpg and the preview window comes up blank and states there's an error. I can perform the suggested steps of copying it over to a new image and then saving it out from there with no issues. I just thought I 'd throw in how I've run into this issue more than 10 years after the original poster and that the HP scan seems to be creating the erroneous data. Thanks, Len
