For quite awhile I have been using Google's Image search to find pictures to use for reference for my artwork. In general, after I found appropriate pictures, I would either download the picture, or copy it to my clipboard or selected the "save as" option.

However, I have found that it is much easier and quicker to simply click and drag the image directly from my browser and then drop it into Xtreme. This saves time and avoids all of the other steps mentioned above. Then, I either use the picture(s) as reference, or in some cases, trace over the image so that I can incorporate it into my drawing.
