[thelist] images - dropshadows & diagonal lines

[Bob Meetin]

Hi, two problems - visit www.dottedi.biz/codesamples/images.html

1) I created an image using GIMP and added a dropshadow.  Displayed in 
gimp or photoshop the dropshadow looks good. Displayed on the desktop or 
through a browser the shadow displays as solid black.  That "ain't" right.

2) What is the technique the take an image, rotate it a couple degrees 
left or right, then resave and get a reasonably good looking image 
without jagged edges where the pixels break up?  Something to do with 
anti-aliasing?

I want to do something similar to the Managing Contents image on this 
page: http://www.thepixelage.com/
