You can all so take a photo with you camera.
You will need to upload your photos to photo shop , photo bucket. I use photo bucket (is free & on-line photo storage) once you have uploaded to there just click on the photo & there will be a few different options links etc etc there is a (direct link) click on that & it will say coped then when you right a post click on insert media just paste that link & the size 350 - 350 is standard.
