Hi Carlow, I didn't find that your technique would work for me. In the end I had to place both images into my file, then group them (in the arrangement I wanted to have them) and then copy them and paste inside.
The reason I wanted to put multiple items into one image box, was so I could use my image box to mask out unwanted areas of the grouped images, but using the same shape to mask all the images.
In my example i have two portrait shots of two men which I have placed side by side, I then placed the grouped images into a image box which has a curve on the bottom edge. Once placed inside the curved image box, both images are framed by the same continuos curve.
This is what I meant in my initial enquiry. It was only because I grouped these images that this was possible - if
I tried to pcopy and paste each image into my curved box individually, this would not work - Indesign only lets me have one image in a image box at a time.
Of course, with my method, I am unable to move each image individually once placed within the curved box. Perhaps there is a better way of doing this?
