When designing an image with a transparent background in Photoshop, you save it for web as a gif and select the matte color so that the edges of your image at least match up with the page background. I am working on a navigation system with rollover effects in Imageready. Its basically several lines of text that change colors when rolled over, and the background is transparent. The problem is that the nav system looks off when I throw it on my page, I'm seeing the little dots of white along the edges of the word. In Imageready when I save it optimized for web, I am saving it as a 32 color gif but have no matte options like I do when saving for web in Photoshop. Is there a way I can apply a matte to it as a PSD before opening it in Imageready to save it optimized as an html file? Or, is there a way to add the matte when saving it optimized in Imageready?
On your optimazation pallet you need to click on the circle with an arrow on it in the top right corner. Your first option is options. Click it. This will show gif transparency options when the slice or image is set to gif. you have a transparency checkbox and a matte dropdown.
The best way to get rid of your white specks (if the transparency didn't work well) is to open the image in photoshop and manually remove the offending pixels. Don't save for the web. Just save it.
