I have created a Photoshop image that I started with a 25 pixel grid that all objects in the image are aligned to. At the end of it I actually decided I like the grid as part of the visible artwork. I realize it is not that much work to go ahead and draw straight lines on top of all the grid lines but it got me thinking...is there a way to actually just convert the grid so it is part of the flattened artwork? For example if I want to save the image as a .tiff to be opened in other graphics programs that wouldn't display the photoshop grid. If it isn't possible (which I can't see that it is) I think it would be a good option to have.
