SVN repository problem

Hi. I just get a link to my SVN repository and I’ve got some problems.

Where I must upload a .php and .txt file? To trunk/1.0.3/ or to /trunk/? How to do, that the version will be printed in the search: check it! – and 1.0.3 will be current version, no “other version” at right bottom box.

Also, where I have to uplaod screenshots? I upload screenshot-1.png and screenshot-2.png to tags/1.0.3/ and it’s not displaying it.
