END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

I believe it was requested at 6,000 x 6,000.

 Hope that's it!

Not an easy task, given the way the white fades slowly to blue in many places - determining the cut off point and edge quality is going to be up to each artist and will look subtly different depending upon who does it.

There is no way to get a sharp edge, so I gave it a soft edge and if it's not what you envisioned - you may need to cut it out yourself with any image editor at all  (they all should have tools to select by color!)

Here's my best effort:

I used a value of 20 for tolerance in rgb variations and a 1 pixel feathered edge.

Hope it works for you 

just received the 15$
i will silently use it for paying the hosting bills, thank you for your generousity bib and delicieux

if this is going to be something like ebay, we have to make it other ways

You can also try rendering this:

}

A few more gradient points, with the opacity linked gives a pretty solid transparent rendering version.
