Must have photo stored ONLINE somewhere, photo bucket, picasa,etc.
Must know how to retrieve the URL of individual photo.
Open the edit box, it must show: Screensize, Format mode, Format, Message Icon, etc.
Format mode, pull down the arrow, go to prompt.
now, get that URL copied via copy/paste stuff.
Format line see the square little yellow box with what look like mountains, 4th from right , click on it, insert URL
I then switch back to Basic in that Format Mode box to do
fonts,
size ,
colors, and typing.
Good luck, hope this is clear and not muddy.
Photo by the way is from today's issue of my blog (see sig line for full address of blog) I just found and copied the URL by right clicking on the photo at the blog. (Ok, that might be about as clear as mud. SIGHHHH Sorry)
