The Dink Network

Almost finished my mapping but wanted to add some new/changed graphics...can someone pls give me specific instructions on how to put the new graphics into my dmod (a tad technologically challenged here...)I am not sure how to save so transparency is kept (only ever used .gif files for transparency not bitmaps). I use paint shop pro for images. Then where do I save the new ones I made so I can use them as sprites... also how do I access the Dink original sprites and make changes to them? Last question is I also would like to know if anyone has any really simple scripting information - I see ppl speak of Dinkc - where would I get a copy of that or anything that explains in simple terms how to do this. Just need some starting tips to what things mean... then I can play and learn.
Thanks heaps to anyone that has the time and inclination to help a real noooooooooooob :0) who is dying to get a dmod finished
