Ethan Marcotte has raised an issue about Fluid Grids, that working with non-fixed layouts can be more difficult once you introduce fixed-width elements into them. By default, an image element that’s sized at, say, 500px doesn’t exactly play nicely with an container that can be as large as 800px, but as small as 100px. What’s a designer to do?

He has wriiten a little script that makes Fluid Images. In short, it cycles through your document, swaps out the images for a transparent GIF, and applies the AlphaImageLoader property to each one. Then, whenever the window’s resized, the script automatically recalculates the proper, proportional height and width of the image, and resizes the spacer graphic accordingly. You can see it in action, and download the script.
