I need that Translation Tool include the reference code into affected entry (fourth).
Sorry, I don't understand the question. Can you please quote the section number and the part that is the problem, then tell us what you need to do, so that we can see what is required?
It is not translatable "Dialog-information.png".
Entry affected at this page is the fourth or better Applications/Education/17
Ah - you mean that you want "Information" to be replaced by your language? The way to do that is to go to http://userbase.kde.org/index.php?title=Template:Info&action=edit and copy the code. Then start a new page called Template:Info/ca, paste in the code and edit the heading. You now have a template for your future needs. You can do the same for any of the box templates which you'll find listed at User:Annew/Snippets#Boxes
