Besides the compiler error, did you mean to return an opposite result from IMAGE Exist(1) as your code above does?
So, if you had the code:
If IMAGE EXIST(1)=1
` image does exist
Else
` image does not exist
Endif
You're are just pointing out that IMAGE EXIST did not work at all for you no matter how you used it?
It worked fine for me under 7.4 as I use that command for my gui work.
If you used that code above to get a positive result, 1, to indicate that your image did exist, then I can see why you program "may" have crashed. If it continued thinking a image did exist, but it really didn't, and you ran some code that needed the image to function correctly, then I can see it crashing because of that.
