The question of how to embed a picture was answered already. Let me encourage all users to really use this feature, which is much more efficient and appealing than posting just the link to the image.
Compare http://www.n-simon.de/doc/momo_50/pics/showc4d_gait_43.gif
with this:

Here is an example with the code used: (extra spaces before and between "greater thans" so it would not execute, Do not use them like that in actual use.)

You will have to host the image somewhere. I placed my example code as a code block by putting two spaces before it so it would not actually load the image in this example.

If someone posts a question with a link like http://tinypic.com/r/14bib77/6 and I want to edit the question to embed the image I get
and that looks really ugly. Is there anything I can do besides re-uploading the image?

I embedded that _exact_ preview, in a Question a day or so, and had no difficulty with it being off the right hand side.

@Walter, you tried to embed the "exact preview" but you didn't. The question is here:
http://www.mathworks.com/matlabcentral/answers/38620-processing-image-with-deconvolution
Basically there are two images: http://tinypic.com/r/2u95qwg/6 and http://tinypic.com/r/14bib77/6 You embedded the 2u95qwg image twice. If I embed that image it works for me also. The 14bib77 image does not work.

Now pictures can be uploaded directly in the forum, see: http://www.mathworks.com/matlabcentral/answers/87583#answer_97176Y . A great step to improve the usability of the forum!

This is completely unrelated to this question. Read this https://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer
After that, post this as your own question (don't forget to have a proper layout of your post, see this link: https://www.mathworks.com/matlabcentral/answers/help/rtc#rtc_summary )
This answer will be deleted shortly.
