TOPIC: how to change Details and Register buttons legenda

Hello. I have an italian website, and I need to change the Details and Register buttons legenda, respectively to Dettagli and Registrati . How could it be possible ?

The text seen in those buttons is part of the image. So you'll need to actually change the image. The course files (with no text) is included in the DT Reg package. Here is what the readme file says:

- Image Source Files (image_sources.zip)

DT Register has 8 different color packages for the various buttons and icons used on the frontend. Here in this unzipped DT Register package you will find a zip file image_sources.zip. If you want to change the text for these buttons, unzip this file and you will find a blank PNG button image of each size and color. Put your own text on these images, save your new image using the exact filenames used in the component, then manually upload over top of the original images at:
/components/com_dtregister/assets/images/

thank you. I like to advice that I was able to post and to comment ONLY using Firefox 7. If I use IE9, all the processes to upload tickets and\or posts SEEMS to go on, but actually fail. In other words, I get "OK you have posted", but actually nothing is uploaded.
In fact , for this post, I solved intuitively using Firefox.
Thks once more.
