Dear Neil

I would prefer to have the image stored as file but its only temporary data. 
You better watch what someone else says to this point.

if you take a look into the latex.1.2.1.py you find these lines:
(http://moinmoin.wikiwikiweb.de:8000/
ProcessorMarket?action=AttachFile&amp;do=get&amp;target=latex.1.2.1.py)

        pagename=formatter.page.page_name
        url=AttachFile.getAttachUrl(pagename,imgname+'.png',request)
        attach_dir=AttachFile.getAttachDir(pagename,create=1)

os.system("%(convert)s -crop 0x0 -density 120x120 %(vartmp)s/%(imgname)s.ps %
(outpath)s" % {
            "convert": config_external_convert,
            "vartmp": vartmp,
            "outpath": attach_dir+'/'+imgname+'.png',
            "imgname": imgname,
        })

get it in the middle:
 request.write(formatter.image(src="%s" % url, alt=texstr, align='absmiddle'))
