I've been using Sigil for quite a few years, usually by exporting from InDesign to epub and then cleaning up using Sigil. Occasionally I've needed to add images, and never had a problem - until now. Now I get the message "you don't have permission to open this file." I'm the creator of the files, and I've double checked the permissions within the file, the file works in every other program (InDesign, Illustrator, Photoshop) just fine, but can't be imported into Sigil or Calibre, for that matter. I tried adding the file directly to the ebook via opening the epub using zip, and adding the file, and it shows up there just fine, and even works in the html using Dreamweaver. But even added that way, the file can't be placed on a Sigil page. What's up???? Any ideas???
