m1k1o/blog is a lightweight self-hosted facebook-styled PHP blog. Errors from functions `imagecreatefrom*` and `image*`

m1k1o/blog is a lightweight self-hosted facebook-styled PHP blog. Errors from functions imagecreatefrom and image have not been checked properly. Although PHP issued warnings and the upload function returned false, the original file (that could contain a malicious payload) was kept on the disk.

Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.
