Yes. But I don't think that the image tag is the problem. I tried to 
change the HTML factory in StructuredText.py

from:

def HTML(aStructuredString, level=1, header=1):
     st = Basic(aStructuredString)
     doc = DocumentImages(st)
     return HTMLNGImages(doc,header=header,level=level)

to:

def HTML(aStructuredString, level=1, header=1):
     st = Basic(aStructuredString)
     doc = Document(st)
     return HTMLNG(doc,header=header,level=level)

So that it would use the old class.

But that changed nothing. It still rendered the html image tag as an error.

Also in the DocumentWithImages.py there is the regex:

     def doc_img(
         self, s,
         expr1=re.compile('\"([ 
_a-zA-Z0-9*.:/;,\-\n\~]+)\":img:([a-zA-Z0-9\_\-.:/;,\n\~]+)').search,
         expr2=re.compile('\"([ 
_a-zA-Z0-9*.:/;,\-\n\~]+)\":img:([a-zA-Z0-9\_\-.:/;,\n\~]+):([a-zA-Z0-9_\-.:/;,\n\~]+)').search
         ):

Suggesting at least that images should have the ":img:" to be recognised 
as an image tag.

So my second guess was that it is the in the ctag() function at line 335 
in ClassicStructuredText.py that the problem was. But I cannot find any 
problems with the regexs. Also a diff didn't show any significant 
changes in that file from 2.51 to 2.61

I don't understand it. Inline code should 'look like this'.

If there is no space before, it should not render as code.

ie. a tag='like this' should not render as code as there is no 
whitespace before it.

To quote the source:

- Text enclosed single quotes (with white-space to the left of the
   first quote and whitespace or punctuation to the right of the second 
quote) is treated as example code.

Ay, that sucks. Customers have been using it for 2-3 years now. And they 
have many many documents. I could write a converter, for converting it 
into the new image tag, but that would suck too.
