About Image Backgrounds:
W & B - Images created with a white or black background do not have this problem. These gifs have crisper edges and tend to appear to have more depth. If you use a white or black background on your website, these are always your best choice, when available.
L ( light ) - On the images marked with L, some of the fringe pixels ( 1/2 & 1/2 ) have been removed but not all of them. This allows us to maintain sharp edges and yet still have a transparent background. Because many of the fringe pixels are removed, the image can be used on any light colored background without a negative effect to the appearance. However, if you use the image on a web page with a black or dark background the remaining 1/2 & 1/2 pixels will show up and the halo effect will return.
T ( transparent ) - 95 to 100% of all fringe pixels ( 1/2 & 1/2 ) have been removed. This allows T images to be used on any color backgrounds. However, the lighter ( especially white ) the background color the clearer the ragged edges of the image appear. The darker the background color the crisper and more uniform the edges of the image will seem.
In Conclusion - It would be best if we could create every image with the exact color or image of your background. That way they would be an exact match with crisp clear edges. Since there are tens of thousands of different color backgrounds on web sites, that's not very practical. However, using the information above you should be able to choose images that are a good match an hopefully will enhance the appearance of your website.
