Re: High Resolution Images

Does the maximum uploaded file size directive in php.ini refuse upload, or cut the file off at the maximum? If you're uploading via a browser, it *might* be chopping it off, resulting in an invalid file. Try *JUST* uploading the file and saving it to disk, then try downloading & saving that file to disk... compare file sizes, and try to open the file. If all this works, then you can rule out a file size issue, and look at other issues, like a potential bug with large files or large resolutions.
