file_exists() function is not working in CI Helper

As far as I know, file_exists() doesn't support URL wrappers (well, since php version 5 some are supported), so you should use filesystem path instead of URL. Nevertheless, if you really want to check if URL exists, you can do it with fopen() (of course - only if allow_url_fopen is allowed in your php configuration):

Code:

if (fopen($ImgLoc, 'r'))
{
    // exists
}
else
{
    // nope...
}
