When saving JPEG files to the TourwriterData folder, please ensure these are saved in the JPEG Baseline format, not JPEG Progressive, format. Tourwriter requires images to be in Baseline format in order to export to MS Word.
JPEGs come in two types: Baseline and Progressive.
A Baseline JPEG is an image created using the JPEG compression algorithm that will start to display the image as the data is made available, line by line. In a web browser, you can see JPEG images that are in baseline format when you see it slowly showing up, from the top of the image, to the bottom of it.
A Progressive JPEG displays an image in such a way that it shows a blurry/low-quality photo in its entirety, and then becomes clearer as the image downloads.
