Okay, for the email just fire up picasa and look for a send email link! I think you can do it from right clicking a particular pic and choosing send email! You might have to search help..
As for putting pics up on DA, look at the top green bar on a DA pg and see where it says your user name then devs from others that you watch, then announcements or journals, then replys and comment from DA peeps, then the SUBMIT button.. Click that and a window drops down, top option is submit art!! You need to have a file ready to submit or upload.. When you upload them one of the questions will be about watermarking the pics, do this unless you are confident that it is okay for someone to use your pic without permission.. The rest of it is pretty basic.. You can also look under the little arrow on the top left beside the word DeviantArt and go to bottom of window and it says "HELP and FAQ" There is a search box along with choices of what you want to know about, just type art submissions into box and it should give you a step by step on how to submit your art.. You probably want to make a folder in your docs folder called Deviantart and then put subfolders in it for your different types of art. Put digital pics in there and upload from there.. Also after submitting, you can organize your gallery into folders of diff types of pic sets or art styles or whatever you like... I am gonna copy this and put it into a note and send it to you that way too.. Notes show up as an envelope in the green bar at top with the submit button.. Have fun..
