I just need a picture from the website and a link..it doesn't actually have to be "under the tree"...trying to Keep it Simple..LOL
Photoshop, MS Paint, CorelDraw, Illustrator, basically any image editing softwareIf you use a Windows PC and you don't edit graphics often, click Start and go to Paint. Then open the background image in Paint. Then you can drag your second image into paint and place it under the tree. Click Save and then upload to your preferred image hosting site (Imageshack, Photobucket, Imgur, etc)
I won't go into cropping out backgrounds or anything but that should be the quickest way to do it if you have limited photo-editing experience
Or just pm me both your Tree pic and your Apollo pic and I'll do it for you really quick w/ transparencies, I have a spare minute.
