Ok, this is a workaround to use till the release of the 6.2.2 version.

Using a SSL port different of 443 causes malfunction in avatar pictures in several places.

1. ViewProfile module: after installation of the module in a page change the scr part of the default profile template adding the full address of the site:
   Instead src="[PROFILE:PHOTO]" use src="https://www.domain.com:8446/profilepic.ashx?userId=[User:USERID]&h=80&w=80" where 8446 is the port (I use this one)
2. Message Center module: go to the view.ascx file in \DestopModules\CoreMessaging and search for this line:
   profilePicHandler: '<% = DotNetNuke.Common.Globals.UserProfilePicFormattedUrl() %>' and change it for this one: profilePicHandler: 'https://www.domain.com:8446/profilepic.ashx?userId='+<%= ModuleContext.PortalSettings.UserId %>+'&h=32&w=32' (thank's Cathal)
3. Buttons up on the right corner: i don't know yet

Hope this helps

Finally I reported theese two cases as bugs:
http://support.dotnetnuke.com/issue/ViewIssue.aspx?id=21911&PROJID=2
http://support.dotnetnuke.com/issue/ViewIssue.aspx?id=21912&PROJID=2

After finding this:
http://www.dotnetnuke.com/Resources/Forums/forumid/108/threadid/368067/scope/posts/threadpage/2.aspx

Journal pics fail tooo.

This is the address you can see in the image properties. Another time without the SSL port I used in site settings:
https://www.doamin.com/ProfilePic.ashx?UserId=1&w=32&h=32

Any idea?

If I use the address with the correct port it shows me the image:
https://www.domain.com:8445/profilepic.ashx?userId=1&h=32&w=32
So, problem is that the part that calls profilepic.aspx is not sending the correct address I set as SSL in Site Settings page.

If I use in the navigator the second address:
https://www.domain.com:8445/LinkClick.aspx?fileticket=oN6LKOgkSVI%3d
It redirects me to the right address of the image profile, but without SSL:
http://www.domain.com/Portals/_default/Users/001/01/1/Logo%20Carril%20Circular.png
So problem could be that LinkClick.aspx is not using the SSL address when it generates the URL. It generates just the relative path that is what I can se when I look at the code page in the navigator:
<img alt="Profile Avatar" width="120" height="120" src="/LinkClick.aspx?fileticket=oN6LKOgkSVI%3d" />

Any idea about where can I change the profilepic.ashx and LoginClick.aspx code to solve the problem?

Thank's a lot
