Pondering switching from expen$ive Photoshop to free Paint.Net, but want to be able to read all your Photoshop files?
Just download this plugin, unzip and copy the DLL into the Paint.Net Filetypes folder. Easy.
Caveat: it doesn’t support absolutely everything in PSD files flawlessly. Discussion here. But the files I’ve been dabbling with (actually converted from CPT to PSD using an ancient copy of Corel Photopaint) work fine.
