I just made my first blurb book through LR. when I was exporting the book to blurb, it said there were 3 images that had transparency and would not be included in the book. When I googled this issue, I found that this probably happened because I needed to flatten a couple images and try to reimport. I don't know how to flatten it any further. I flatten my image after editing in PS, but then it still has a tiff name when I save it back to LR. I can't find anywhere in LR where I can flatten it further or change the file type if that's what needs to happen. It doesn't even happen every time I use PS. Is flattening the image in photoshop prior to saving back to LR not enough?
Should I save as a jpeg and then reimport it to LR from my desktop? If I "save as" and make it a jpeg, it looks like it's saving it in LR, but it doesn't show up there. Hope this makes sense and thank you!
