Ok i have it figured out ... i can convert images to base64 strings, which gives me a string I can manipulate using simple 'eq' operators.
So using a scheduled task, every 5 minutes, I take the current cabcam.jpg (thats the name of the file that's displayed on the web page) and convert it to base64 using the function ImageWriteBase64() . That string, I compare to the one I did 5 minutes ago. If they're different, all's well and good, so do nothing, except save the base64 string to use in 5 minutes' time. If the base64 strings are the same, we have a winner! Send me an email with all the details and I know within 5 minutes when the thing went haywire. Now all i have to do is write the functionality so it doesnt keep sending me emails every 5 minutes after that. Thanks for your help everyone. I have a little bit of tweaking to get round a couple more hiccups, but i have the basis of the method I can use.
