All you need to do is go to a place that lets you post your pictures on-line AND link to them. I use picturetrail.com.
Upload your pictures. Then view them. Once you are on a picture (the big one on the right-in picturetrail)...right click on it and "copy picture location"
Come here in the message area and type:
(img src="paste in your picture location here")
replace the ( & ) with < & >
***** The Webmaster requests pictures be kept small (under 50K). I sized this one down to 12K.
