lpr- there will be many on the forum who are more tech savvy than me- but since I just struggled with this last night, I'm going to try to get you going.
After you've put your photos in your computer, you can go to photobucket and register (or a similar image hosting site). If you follow their instructions you'll have pix on that site. Copy where it says "direct link", then paste that into your post here.
That should work- Good luck! Easier than it sounds.
