Flavio what are the limits on image size.
I don't know, there is no hard cap.
also can you make a warning that image size has been exceeded
No because it just crashes the server, if it crashes I can't say "ehy, don't crash and show this instead", it crashes and that's it. It's kind of like a middle finger
Now to be realistic this still shouldn't be an issue because to make it crash I had to upload pictures that were 9MB each, 4000*4000px or something, super high definition (the guys that take pics of people at the track are no joke with cameras). In a real application this shouldn't happen, I haven't seen anyone posting pictures of such stupid high quality, it was some kind of heavy stress test on my part - reason being it's generally good for an admin/developer to know the server limits, even though in this case I can't really draw an accurate line so to speak.
