I found that on Saturday and added the UNIX files from the TeX Live  
2007 DVD to the MiKTeX installation. This particular error goes away,  
but it's still not possible to work with PNG, TIFF, GIF, or JPEG  
format images. Even TeX Live 2007 fails:

Reason is obviously that dvips creates a bad zzFile.ps file: gv can't  
display it, it shows in a window the same error from gs as cited  
above. Running Apple's pstopdf on zzFile.ps I get this error:

	%%[ Error: syntaxerror; OffendingCommand: binary token, type=137 ]%%
	%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
	%%[ Warning: PostScript error. No PDF file produced. ] %%
	pstopdf failed on file zzFile.ps with error code -31000

PStill reports:

It makes me believe that latex is not correctly embedding graphics  
files anymore ... Is the use of the command line option ``-src- 
specials´´ now mandatory?


Right now it seems that TeX4ht only works fine with graphics as PS  
files ... on Mac OS X.
