Thank you, with your pictures, now I can make it work.
Here's how my config currently looks like
and when mouse over is on an album (in this case, TAM no Fukubukuro)
Group:$if2(%album%,@skip)
Sort:$num(%gb_playlist_number%,10)
Type: Vertical Scroll
Size: 120x114
$puts(imagePath,
$if($cwb_fileexists($replace(%path%,%filename_ext%,)cover.jpg),
$replace(%path%,%filename_ext%,)cover.jpg,
$if($cwb_fileexists($replace(%path%,%directory%\%filename_ext%,)cover.jpg),
$replace(%path%,%directory%\%filename_ext%,)cover.jpg,
'.\components\default.png'
)
)
)
$draw_image(3,4,$eval(%gb_width%-2),$eval(%gb_height%-8),
'.\components\cdcaseck3.png',
255,
nokeepaspect
)
$draw_image(16,6,$eval(%gb_width%-18),$eval(%gb_height%-12),
$get(imagePath),
$if(%gb_mouse_over%,150,255),
nokeepaspect
)
$draw_image(16,6,$eval(%gb_width%-18),$eval(%gb_height%-12),
'.\components\glareyo0.png',
50,
nokeepaspect
)
$if(%gb_focused%,
,
$gp_set_font(Tahoma,9,b)
$gp_set_text_rendering_hint(ct)
$gp_set_smoothing_mode(1)
$gp_set_string_format(center,center)
$if(%gb_mouse_over%,
$gp_set_pen(255-255-255-255,3,,bevel)
$gp_set_brush(255-0-0-0),
$gp_set_pen(255-0-0-0,3,,bevel)
$gp_set_brush(255-255-255-255)
)
$gp_draw_string_path(%gb_group%,12,,4,4,$eval(%gb_width%-6),$eval(%gb_height%-6))
)
EDIT: Forget to mention that you need the CD case image and glare image in joaotavela's post above.
