1) By using indexed colors, you are making sure that the colors in the image remain constant. When you scale the image in RGB mode, the scaling process can add more colors to your image as it tries to anti-alias the image while it scales. However, by converting the image to indexed first, you're fixing the colors that will be used in the image. 2) I don't think using 288 instead of 300 has anything to do with the aspect ration of the image or any text in the image. I think the statement that using 288 is safer because it maintains the proportions of the image is a mis-statement. However, as wj pointed out you will occasionally get blocks of five pixels instead of all blocks of four. This may not have any affect on the image unless you have sharp lines that are non-perpendiculat (vertical or horizontal). In that case, you will start to see jaggies in the lines because of the occasional odd size block of pixels. This will be more noticeable in images with text because text, more than most other types of images has lots of sharp lines at non-perpendicular angles. By using an integral multiple of the original resolution, you will reduce the amount of aliasing in your target image. . -- not necessarily stoned... just beautiful.
