getimagesize error
===

My upload/crop function is working almost how I want it. Except Im having to refresh my page to show the uploaded image..And then when I delete the image using the delete button futher down my code, I get the following 2 errors showing in my header. And the upload form doesn't show up again unless I refresh the page, then the following errors dissapear from view until I delete the uploaded image again.

Here is the two errors and then the code with the getimagesize functions marked as bold.


      Warning: getimagesize(imgs/pic7.jpg) [function.getimagesize]: failed to open stream: No such file or directory in ----- on line 48

This is the area of the issue with the two errors marked as bold -
