RE: Unable to Launch an external application from AX 7

Martin got the point correctly, running an external application from a browser to display an item image is not the correct approach. You may add images for released products using standard functionality. Also you can use Document attachment where images, document could be attached to almost any records in AX.

Handling images from a technical point of view:
