Finally! How many hours have I spent debugging sessions without UI with MESSAGEs and ERRORs… The good old days.

If you have done that, like me, then you will probably agree that it was not the most elegant way of finding the source of the problem. Have you ever forgotten to delete a funny MESSAGE after a session debugging with that method and had the client bring it up? I know I have.

What the web service did was generate the image file, code it into base64 and send the “translated” info. What does this mean? Well, it means receiving a string of text 4.000 characters long. Not as visual as expected…

But let us not lose hope! This rang a bell in my head. I could have sworn I had seen something similar previously in my collection. So after searching through the personal box of code and the internet (a line from here, a line from there…) what I discovered was this:
