How to change style logo
Changing Logo
Copy your logo image to directory styles/{style}/imageset/ (replace {style} with style name), open imageset.cfg in a text editor, find line that starts with this:
and replace it with a line like this:
Replace logo.png with your logo file name (note: it is case sensitive, so Logo.png and logo.png are not the same), 52 with your image height, 289 with your image width.
Problems
If after editing imageset.cfg you do not see changes, go to admin control panel and click "styles" tab, "imagesets" link on left and refresh your imageset.
If after editing imageset.cfg and refreshing imageset your logo has disappeared, most likely you have entered incorrect file name. File names are case sensitive, so Logo.png, logo.png and logo.PNG are not the same. Fix error in imageset.cfg
If after editing imageset.cfg your logo has incorrect size, you probably have entered incorrect values in imageset.cfg. Format is simple: keyword = file*height*width, you might have mixed up height and width.
