the easiest method is to use Photobucket.com It's free. Upload your photo there, then copy the HTML line and paste right in with your text , NOT in any link. This method enables you to post multiple pictures on the same post regardless of picture size.

What is the name of the purple and white one in your second picture that looks a lot like the one I am trying to find the name of?
Thank you for you help on the picture. I put it on snap fish but I think next time I will try what you said with photo bucket.

The second is 'Wabash'. It has a light border on the falls. I have a second iris with similar color combo but no light edge on the falls.
