losing images on conversion (epub/fb2)

[rbruce1314]

I have regularly used epub inputs from various sources (particularly archive.org) to get to fb2 output for my zx reader. All has gone well including faultless inclusion of images where appropriate.

But this time I inputted an epub book, converted it to fb2 and it refused to include the images (1.9M v 5.6M). Calling up the epub in calibre ebook reader shows the images present and correct, but there are none in the conversion......

Have I changed a preference somewhere without noticing - indeed IS there a preference to leave out images? I've checked all I can in preferences and can't find anything to correct, so where do I go from here??
