Why does this figure do not appear?

I add a Picture "GaussBonnet with Jpeg format to the following question but it does not work.

(Some possible obstructions to ) Limit cycles as closed geodesics(3)

Can one help me to resolve this problem?

• I have edited your post, maybe it has the form you wanted to achieve. (And maybe not, but at least some pictures are displayed now.) So maybe you might add a link to revision where it did not work and also the source of that revision - so that the question on meta still illustrates what is (was?) the problem. – Martin Sleziak Jun 10 '18 at 9:38
• @MartinSleziak Thank you very much for your edit. When I clique on the picture, it does not appear. In your computer, does the picture appear automatically? Can you see this picture? – Ali Taghavi Jun 10 '18 at 9:41
• BTW the two pictures look the same to me. (Although the links are different - in the current revision i.stack.imgur.com/YxQiy.jpg and i.stack.imgur.com/cxaM7.jpg ) Did I miss some difference? – Martin Sleziak Jun 10 '18 at 9:41
• I don't really understand your comment. Are you saying that after my edit you still do not see the pictures? – Martin Sleziak Jun 10 '18 at 9:43
• @MartinSleziak I tried both with computer and my Phone. when I clique on the link "GaussBonnet" It try to enter i.stack.Imgur.com/.... but it fail. any Way thank you for your help. Yes the two picture are the same. I added the second one because the first one did not work. Now, according to your comment I realize that the problem is mine(by my phone and computer). – Ali Taghavi Jun 10 '18 at 9:50

It is difficult to give some advice since it is not clear what went wrong. The OP has confirmed in the meantime that now the images are visible in the post. As you can see in the revision history, all I did was adding the missing "!".

If a picture is uploaded through the editor, the Stack Exchange software should take care of the correct syntax for the picture. Of course, it is possible that when editing the post something goes wrong. Solution is either to upload picture again or try to edit the post into correct syntax.

As you can see in the section on images in the Markdown help, it is possible to use HTML image syntax. Markdown syntax for images can be ![text](url) or ![text][1] where 1 refers to link.

Example: ![MathOveflow logo](https://i.stack.imgur.com/B3C50.png)

The same can be obtained by

![MathOveflow logo][1]

However, as already mentioned, probably the best strategy is to upload pictures through the editor and leave it up to the software that the correct syntax for inclusion of the pictures is used.
