All my icons are saved as TGA, so i can put them right into my maps, and the program i use (graphicsgale) doesnt have a way to save to .blp and i have way to many to change, i have about 50 some icons related to my LotR minas tirith map and disabled for all of them, in my style not blizz, plus the save name doesnt say dis and disnt or whatever and there are to many to change, any weay around it?
first you have to make them BLP and rewrite them to (BTNname and DISBTNname - i know it is bit of work if you already got lots of icons)
and to submit them on the site you need to go to 'add/update resources' and press icons then you search in your computer for the icon (the BLP icon) and put it and also the DISBTN (again the blp) then you submit icons
You can convert .tga/.jpeg or .bmp to .blp with Image Extractor II or Wc3 Viewer. Also before converting .jpeg, .bmp or .tga make sure they are 32bits or if lower than an opaque alpha channel is needed.
