Converting to Mobi ignores image links

[atjnjk]

Recently, I noticed that image links in converted Mobi files aren't clickable. I made this test: convert a Mobi file with working image links to Epub, then convert that Epub to Mobi. The new Mobi file shows images but they are not links. Is this a bug? (I'm using calibre v0.7.48.)

The epub to mobi conversion's log file has some lines like this:

Ignoring redundant href: SoT_split_002.html#calibre_toc_6 in 'PROLOGUE'
Ignoring redundant href: SoT_split_002.html#calibre_toc_7 in 'CHAPTER 1'
Ignoring redundant href: SoT_split_002.html#calibre_toc_8 in 'CHAPTER 1'
Ignoring redundant href: SoT_split_002.html#calibre_toc_9 in 'CHAPTER 2'
Ignoring redundant href: SoT_split_002.html#calibre_toc_10 in 'CHAPTER 2'
Ignoring redundant href: SoT_split_009.html in 'Prologue'
Ignoring redundant href: SoT_split_009.html in 'Prologue'
Ignoring redundant href: SoT_split_012.html in 'CHAPTER 1'
Ignoring redundant href: SoT_split_012.html in 'CHAPTER 1'
Ignoring redundant href: SoT_split_013.html in 'CHAPTER 2'
Ignoring redundant href: SoT_split_013.html in 'CHAPTER 2'

This is some image links in the Epub:

<p class="calibre23"><a class="calibre16" href="../Text/SoT_split_009.html#filepos12960"><span class="calibre17"><img alt="Previous" border="0" class="calibre29" src="../Images/00006.jpg" title="Previous" /></span></a> <a class="calibre16" href="../Text/SoT_split_002.html#filepos427"><span class="calibre17"><img alt="Top" border="0" class="calibre29" src="../Images/00004.jpg" title="Top" /></span></a> <a class="calibre16" href="../Text/SoT_split_013.html#filepos58059"><span class="calibre17"><img alt="Next" border="0" class="calibre29" src="../Images/00005.jpg" title="Next" /></span></a></p>
