How to combine multiple png icons into one transparent iconset
What software can I use to combine multiple transparent png and icon files into one transparent iconset?
You can use a CSS Sprite generator. There are a few of them out there. You usally just upload all the icons and let the website do the rest.
I make mine by hand. I like having lots of clearly labeled layers so I can find things in the future and maintain the images. Personal preference I suppose.
