I'm trying to create a pdf document (the end result will be a printed advert) and when i use certain images the pdf shows them as a grey box with 2 lines going from corner to corner of the image. The images look fine in INDesign and other Windows applications, and when I switch out the new image for an old one I've used before the pdf includes the images as normal.
Because of this I think the issue may be something to do with the image properties. Looking at the details there are 2 things that appear different between the new ones and the old ones that have worked before. Firstly, the dpi on the new image is a lot greater (51,711 x 51,711 - can that be right?) than any of the ones I've used before. Secondly, the image properties say the new ones were produced using Photoshop, which I don’t have.
Could either of these be the cause of the problem?
I'm using INDesign CS6 and Adobe Acrobat XI Standard if that helps.
Look for a preference in Acrobat: "Show large images".
I tried that and it didn't make a difference. I've also emailed it to a colleague and another device and I still get the same problem.
