Either image51 is not set out it doesn't have a tag. Probably the latter, but the debugger will tell you for sure.

It depends on the app if the bug is that it isn't set or that the app crashes if it isn't set or both.

i set image51.Tag=100 in load page

From the results it sounds like this isn't happening as you think it is. You might want to check the code flow in the debugger to see that it's getting set and not unset.
