Thanks.  
>Will you be incorporating:
As with any Open Source project, the answer depends on who's planning on 
writing the code necessary for a given feature.  My personal criteria for:
  - which features I'll write
  - which features I'd be happy to see patches for
tend to differ.  A lot.  :-)
>1 Insert a bmp, gif, jpg picture into the Insert<Picture menu?
This is an obvious feature for AbiWord.  We've set up all the infrastructure 
for PNG-native graphics internally, so what's required are platform-neutral 
decoders for other raster graphics formats like these.  I believe Matt 
Kimball recently made that task easier before he started working on vector 
graphics support via SVG.  
Since you posted this to abiword-dev, rather than abiword-user, are you 
interested in more specific pointers about where to start adding that code? 
>2 Ability to open, create, save html with gif/jpg? (I see that you can
already save as html)
This isn't really an obvious feature for AbiWord, and the core development 
team is unlikely to tackle it at any time in the foreseeable future.  There 
was a pithy discussion of this on the list not too long ago:
