Possibly, but perhaps not.. Someone should have resonded by now, to your first querey, and the resolution is actually fairly simple. If images are not appearing, then it is possible they have not been included in the original backup, or perhaps they were put elsewhere, or the restore has an error in the restoration string. If the images have been included, but are not showing then all you need do is to relink the images - the simplest solution. In editing mode, select a blank image, then click the insert image button. Go through the normal process of inserting an iage, but when the file picker appears, select "Server Files". This should open the server up and reveal the /Imagenes/ folder. Enter that folder and the image will be there or not. If it is there, then select it, you may get a dialog that asks if you want to duplicate the image, just respond "No" and follow the prompts from there. If the image is not there, then you may have to back out and manually upload them.
Painful, I know, but the only alternative is to upload a zip file to the same course root and unzip, selecting your images from there. A lot quicker than manually doing it. Cheers..
