Hi being a new user and all I was wondering if I could use Photoshop CS to convert pictures to fit and be the proper file extention for wallpaper on a 7130e. I've done a few searches here and couldnt find an answer to my question. I have a themes tool I just downloaded but since I'm really good with photoshop Id rather use it.
As to format, use Save For Web option under the File menu and save as PNG. I use the custom option and restrict file size to 56K to keep the memory space. As to the size, I assume the 7130 is the same as all th 71xx series which is 240 X 260. See this post.
