As the title says
Simply import your Icon(170x170 image, transparent backround and your pic no bigger that a 169x169 circle) into the Image layer, merge layers, apply Bicubic Sampling(I usualy Resize down by 1 then back up by 1 to do this and if it ends upa bit too blurry sharpen the image a bit) to meld the icon and template together so there is no sharp edges, save as dds and you have a SV Icon.
