I have a google website that contains map images that I would like to use in explorer online. When I post the url to the popup, it shows a small red x but no image. What could I possibly have missed. Is there a size limit to the image?
The most common problems are described in the help for editing pop-up windows here: http://help.arcgis.com/en/arcgisexplorer/help/#/Edit_pop_up_window_content/015600000033000000/ "If you want to display an image in the pop-up window, specify the URL to the image you want to display in the Image URL box. You can use either .PNG or .JPG images. HTTPS URLs are not supported in Explorer Online."
Does this explain the problems you're having, or is it something else?
