If I start a new chapter or a new section, preceding it with \cleardoublepage command, which may or may not produce a blank page so that the new chapter or section starts on an odd numbered page (RHS), how can I put an image (with a caption) on that blank page (the LHS), where the numbering is still related to the new section that is starting on the RHS.
By numbering I mean if current chapter is Chapter 2 desired figure naming should be Fig 2.1, 2.2, 2.3.... etc. It would be quite easy to just insert the image, before the new chapter or section is issued, but then the numbering might be Fig 1.1, 1.2, 1.3 etc, since the new chapter hasn't been inserted yet.
If there is no blank page (ie already on a RHS), then the image should go on the next page.
