Attaching a file problems

Hey everyone. I do not seem to be able to attach a file anymore. I always get this message when I attempt to do so:

Thanks for the well wishes. Anyway i guess we can find such birds in Singapore as afterall this is the tropics. However, I certainly hope they do stay in Singapore as due to development, pollution and destruction of habitat may result in the diminishing of species in Singapore. But, at the same time...
