I've been researching this most of the day with no luck, hopefully someone here can provide some insight.
I should preface this by saying that although I am an experience Developer this is my 1st time using Web.
I am designing an Internal Product Maintenance application for a Client using LANSA Webevent and they requested a clickable thumbnail (from a list of Products) which would then take them to that specific Products maintenance screen. All this works great, Images that are available are shown and clickable.
Problem I am having is when an image doesn't exist I need to insert an "Image Not Found" thumbnail. How can I test that the image hasn't shown? I get a box with a red 'x' in it when not found.
Thanks in advance for any help offered.
