ok, cheers. Just to be clear, the download of an image for an individual show is a darn sight better than nothing and perhaps there are people who would really appreciate this level of functionality. I may be in a minority of one.
And if you can write a util that does imagegrab <title> as a standalone, it would not be too hard for someone to write a wrapper to call this for every show in the EPG table.
just my 2c.
