The following is from the TextMaker 2008 user manual.
The question is, where are the properties for the " Save within document" & "Copy to document’s folder" for images? I've looked in both the file->properties dialogue and tools->options dialogue. . . haven't found it.
Right now it saves the image with the document and as far as I can tell that is the only option.
Double click on the picture to open the object properties, then invoke Picture=>File. The 2 options you are looking for are in the lower left corner of that dialog window.
