rubyaim Posts: 757 Joined: 6/22/2005 Status: offline	Background Image dithering - 8/29/2005 2:13:57 I am really out of my element working with images.. Have an image in the background of a table cell and it appears to be dithering when viewed in the browser. The image is the problem and I can't seem to fix it. Have attached a screenshot of what I'm seeing in the browser (may have to go up to 200 - 400% to see the problem clearly), and another of the actual image. It's on an Intranet so I've no URL to post. I'm using FireWorks but really don't know what I'm doing yet (only commenced using it at the start of this month - up until then I used PhotoDraw but my old machine with a copy of this finally wore out ). Basically I need someone to tell me what I've done wrong... Thanks Sally Attachment (1)

I really do appreciate your help The original image was a jpeg ... and of course I'm really not sure what I'm doing in Fireworks yet. After reading your post I went into it and found where the 'exact' palette type is Thanks again for your time Sally (in reply to d a v e)
