File talk:Two circles antihomothetic points radical axis II.svg
About "moving to commons": This image is created as a try of a correction of a one-purpose image, used on Homothetic center. The purpose was to present it as a suggestion for improvement, subject to the original creator's opinions. I'm not sure whether this is the correct license; but I found none for "derived work from a file already at commons, with a creative commons license". I tried to put it as a temporary subfile to my directory; but seemingly there are some special mechanisms for handling images, making this impossible - and also making it impossible even to put up a modification licensed with our licenses for permitting modifications, for just discussing whether or not this is a reasonable modification, without contributing one license out of a fixed and very limited set. Also, it was put here, rather than at my home page.
In short: It is a bit premature to put this into commons. Wait at least until the creator of the original file (User:WillowW) has suggested either to use it, or to make another version.
On the other hand, I would appreciate an explanation of how I properly should have licensed this. I just did what seemed as the best approximation, out of the limited number of alternatives; but it really conveys a feeling of incorrectness. JoergenB (talk) 16:22, 1 November 2010 (UTC)
