How to convert JPG to GIF similar to Photoshop

[sradu]

http://i.imgur.com/ouC0c.png this is a snapshot of the original jpg, a gif created with ImageMagick, and a gif created by Photoshop.

Is it possible to convert the original jpg to gif and make it look like the Photoshop version in ImageMagick?

You will have to give more information as to what you want - the only difference I notice is the middle image has bubbles and the other two do not.

I'm bumping this to make it more clear. The imagemagick created one is much more pixelated, while the photoshop version is smoother.

If you focus on red bubble maker you'll notice that it contains a lot of white pixels, while the photoshop one is a lot smoother. Similarly this can be noticed on the green bubble liquid container.

Quantize NoDither seems to solve it temporarily.
