I got a problem.
I have a script I'm working with ... following a tutorial found on DevArticles.com.
The tutorial can be found here:
Anyway, it seems that the upload script works fine.. except for the JPG checking. I can comment out that section, and it passes the GIF, BMP, and PNG sections. But otherwise gets stuck on JPG. Also.. I just noticed that even though the errors are displayed the file seems to get uploaded anyway
Fatal error: Call to undefined function: imagecreatefromjpeg() in /var/ on line 77
Any ideas?
