Anne-Marie,
Thanks (again) for your reply. I am using CS6 8.0.1 but I have a niggling feeling that the update may not have installed correctly at the time. Do you know of a way I can check, or re-install the update?
The validation notes on this one are indeed Warnings and not errors. I didn't realise the file would be still valid. I am new to all of this and just assumed I needed a clean sheet when validating. That's good news. Here is an example of one of the errors anyway:
WARNING: /Users/Mark/Desktop/LEM-EPUB-TEST-Throwing-121206.epub/OEBPS/image/9781408139554_p072 new_fmt.jpeg: Filename contains spaces. Consider changing filename such that URI escaping is not necessary
Thanks for the link to the Tomaxxi script. I shall Google how to load / run such scripts from InDesign (like I said – I'm a newbie!) and make use of it. A clean sheet would be much more pleasing!
I do have other validation errors that I need to sort but I'll look into these before posting seperate queries.
Many thanks for your time.
Mark.
