looking for antialiasing program for images. Only ones i\'ve found are for text and not pictures. Anyone know any programs that can do it for pictures, or plugins for photoshop etc?
Thnx in advance.

I don\'t understand what you\'re trying to accomplish. When you assemble images in Photoshop you can choose to turn antialiasing on or off, and I think you can adjust it. No plugin needed. Beyond that, the number of jaggies you see in a given image depends on the source capture device, and the resolution of the image. You can maybe soften edges manually using the smudge tool... or just apply the soften filter to the whole image. What are you trying to do?

basically clean up edges in a image.. Very basic image. So using filters like soften. (which doesn\'t seem to be in ps) doesn\'t work to well.. The antialiasing sides are just for certain tools. But aren\'t making any difference.

Check out the PS help menu under Anti-Aliasing. This is what I found, pics not included:
Softening the edges of a selection
You can smooth the hard edges of a selection by anti-aliasing and by feathering.
Anti-aliasing
Smooths the jagged edges of a selection by softening the color transition between edge pixels and background pixels. Since only the edge pixels change, no detail is lost. Anti-aliasing is useful when cutting, copying, and pasting selections to create composite images.
Anti-aliasing is available for the lasso, polygonal lasso, magnetic lasso, rounded rectangle marquee (ImageReady), elliptical marquee, and magic wand tools. (Select a tool to display its options bar.) You must specify this option before using these tools. Once a selection is made, you cannot add anti-aliasing.
Feathering
Blurs edges by building a transition boundary between the selection and its surrounding pixels. This blurring can cause some loss of detail at the edge of the selection.
You can define feathering for the marquee, lasso, polygonal lasso, or magnetic lasso tool as you use the tool, or you can add feathering to an existing selection. Feathering effects become apparent when you move, cut, copy, or fill the selection.
To use anti-aliasing:
1. Select the lasso, polygonal lasso, magnetic lasso, rounded rectangle marquee (ImageReady), elliptical marquee, or magic wand tool.
2. Select Anti-aliased in the options bar.
To define a feathered edge for a selection tool:
1. Select any of the lasso or marquee tools.
2. Enter a Feather value in the options bar. This value defines the width of the feathered edge and can range from 1 to 250 pixels.
To define a feathered edge for an existing selection:
1. Choose Select > Feather.
2. Enter a value for the Feather Radius, and click OK.
Note: A small selection made with a large feather radius may be so faint that its edges are invisible and thus not selectable. If a message appears stating "No pixels are more than 50% selected," either decrease the feather radius or increase the selection\'s size. Or click OK to accept the mask at its current setting and create a selection where you cannot see the edges.

If I understand, you are staring with an image that already has jaggies in it, and you want to make it look more smooth. That\'s going to take a lot of manual manipulation to make it look good. Photoshop certainly does have a soften filter, it\'s called BLUR. Filter > Blur > Blur. However, it may not work for this purpose.
Post the image here, and I\'ll tell you what method I would use to fix it.

what kind of an image is it, a photo or some gif pic you found?

its a very simple black and white image. I tried enlarging the size while using AA then resizing it back. It worked somewhat, i\'ll play around with it

There are many many ways to do this. It sort of depends on what you\'re planning to do with the image. I like this solution because it gives you maximum flexibility.
First I squeezed the levels to get rid of the noise in the black areas. Then I increased the image size x4, and selected the white areas using the Select > Color Range... command. I converted that selection to a path, setting the tolerance to 2 pixels. I did not adjust the path in any way, because I didn\'t feel like doing any work. :) You can see some kinks in it where it was bending around the old huge pixels, but those could be manually tweaked if it\'s important.
I then added a couple layers to accept the new pixels. I stroked the path with pure white, and a 5 pixel brush. That produced the fine high res antialiasing. Then I deleted the old layer, flattened the image, and deleted the path. Resized the image down, and saved as jpg.
Needs work but that sort of depends on what you\'re planning to do with it...

I found another way of doing it. I remembered a little technique i used when i made those jedi vids i did ages ago.
heres the outcome. I\'ll tweak the settings alittle till i\'m happy with the result
-
usually the quickest way to do this would be to blur the image, say around 3 pixels, then drag the levels sliders to the middle.
But seems you fixed it already.
