Not sure what you're trying to show where. Perhaps the attached example can give you an idea. You can use an url to an image and use it to set the background image of a text box. You can use the string with the url as a chart expression and set the Representation option to Image.
how about create a web image viewer and use the image viewer to load and display the image such as jpeg, bmp, tiff and other image formats. and you can also adjust the image size. but not sure whether image with url can be loaded and displayed.
