The danger.gif image - I created it from a couple pieces of clipart, the
doggie and triangle, then created the oval, text etc with gimp, all as
the default resolution. It wasn't intended for print then but is now.
Other than converting to 300dpi in GIMP, how do I ensure that it's good
300dpi, meaning that through the conversion wouldn't GIMP have had to
guess and fill in the missing pixels.
Ah, I think you misunderstand the DPI setting. In this context, it
determines how many of your pixels go into a printed square inch.
Printing this 200x200 pixel image at 300dpi would mean it got printed
only 2/3rds of an inch big.

I suspect this is *not* what you want :)
Do I need to go back to the drawing board and bring it all in as 300dpi?
I recommend, instead of using GIMP for this, import the image into
Inkscape, and use the 'Path->Trace Bitmap' feature to convert it into
a vector graphic. which it's easy to render at any DPI using the
'File->Export bitmap' dialog.
It's slightly more complex than that (the dog may not convert well,
and may require some adjustment). At that point you could make any
touchups you think are needed to the rendered 300dpi image.
If I was making a graphic like this, I would do it all in Inkscape --
this sign contains mainly vector elements.
If you prefer to use only GIMP, then you probably will have to start
from the beginning.
Hope that helps,
David
