Re: PHP & GD open image file error

First off, if you are using the Content-type: header, you can't feed out any HTML. If you use ImageGIF($im); and don't put any HTML after the >? tag it'll probably work. If you want to have the script make the image, then have the browser load it with a IMG tag, leave out that Contenent-type: header. I don't understand directory permissions as well as I probably should, but I've got a directory that I stuff some dynamic thumbnails in, and it is owned by nobody/nobody and is mode 777.
