Onclick handler calls a saveimageshandler() procedure.
saveimageshandler() procedure posts a message to the form.
saveimages() receives the message, do saving routines and destroys all

There might be a possibility of it not working properly, I believe.

Button calls OnClick
OnClick calls SaveImageHandler
SaveImageHandler posts message and returns towards OnClick
Application may handle message and call messagehandler which frees
button before ...
Execution returns to OnClick from saveImagehandler
OnClick returns to Button code which has been freed by now.

Is this a possibility ? IMO OnClick should post message as last code
line following SaveImages call. Then the message will always be
handled after OnClick returns.
