Assets Uploader

[iLogan]

Every now and again when I upload stuff to Assets it gives me this error:

Warning: getimagesize(http://Habbox.com/assets/images/213/1327757536_hxl.png) [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in /home/habbox/public_html/page_functions/functions.StaffUploader.php on line 138


The image doesn't upload.

It shows me that message as well, but with me it uploads the image as well.
