There're some transparent images in my document that Indesign confuses as non-transparent. The links panel says "Transparency: No". But when you open the image in Photoshop, you see that its on a checkered (non-existing) background, and you can flatten it if you want.
I've had similar problem with Indexed color images, I never understood why, but now I have the same with RGB images. Why this happens?
