Sebastian, we'd actually prefer you remove the picture from your signature altogether and put it under your name in your profile (left side area). The information about that is found in the first post in this topic from webguy for the reason:

Photos in the signatures cause an extreme amount of bandwidth because they load hundreds of times where people post multiple times in one thread. Personally I like them and think they add to the sense of community we have here. The issue is the size of the photos and the amount of “LOAD” they cause. The little icons in the signatures really do not cause much load. The photos of personal trailers and or tow rigs do cause quite a bit more load.
To remove the picture, click on "My Controls" and then on the left nav bar under "Personal Profile," click on "Edit Signature."
