[Koha] Koha translation to Spanish

Hi all, I'm doing the translation by myself, since i'm in a hurry about this. I've finished translating the .tmpl archives(templates no?) in OPAC and Intranet html directories I hope this is the way to do it, and I would like to know what is next, how do I make 'em visible or how do I use this new templates, I think I have to put them in the same directory where "en", "fr", etc, directories goes. Isn't it? Another thing...while I'm editing the text, the images aren't shown, I know that I have to change/translate them too, I thing Fireworks program will be okay for that. Will images be displayed as normal when I finish the job? OK thanx J0se
