I've seen a few threads here of people having problems publishing a finished document using the "publish online" feature. Most do not have an answer given but I've noticed a common feature appears to be the size of images, etc enclosed within the document.
I am trying to publish my first indesign document - an 18 page brochure. I always get to 95% uploaded when the publish online fails. Across pages 16/17 I have an image which contains a lot of information. I've reduced the document in dimensions and changed the quality of the image so that it is now only 3.71M (originally over 18M) yet still the document refuses to upload. Meanwhile I am concerned that the image will end up fuzzy.
Please Help! I need to get this document saved asap.
Try exporting the document as a Fixed Layour ePub and see if it's successful or whether it throws up any issues if you validate it which may help you to discover why Publish Online isn't working for you.
