Thanks for the reply...I have tried the different settings...same results.
I see that another member is experiencing a similar issue, but in other browsers. After some additional testing we are getting varied results...
On Firefox...the graphic appears tiny on the first view, but then when we click to another page with the pop-up it goes back to the regular size.
On Chrome, we have no issues that we can find.
On IE...the pop-up just gives us the X and no graphic on IE9 but does not appear at all on IE10.
As for using the html editor, our pop up is only a graphic we uploaded, so we didn't have to use the editor at all..so not sure if that makes a difference or not.
Thanks again for the prompt support!
