I'm trying to modify a script that displays a picture. the problem is that the script gives to options to the users to select a picture, either by uploading the file or by using a url. this will display only the upoaded images:
echo "<img src=\"uploaded/$image\" />";
how can i check if the picture is on the servers or is a url and then display it?
i am guessing that you are trying to make a system where your users can either upload or select an image (like an avatar on a forum system 
)
my suggestion is go ahead and look at your User CP > Edit Avatar section to see how you should set up your code..
then check out www.php.net for $_FILES(file uploads) and search around for help on such scripting
if you already have that part set up, then modify the selection part to enter the information into a database (i.e. fields image,type)(for type URL, make image the full http:// URL, and for type upload, make it just the name of the uploaded image... and echo your image out using the type field)
Is this the only way? the way it works now, when the image is uploaded the location is http://www.domain.com/images/image.jpg
and when the image is from another url is
http://www.domain.com/images/http://www.anotherdomain.com/image.jpg
so i was wondering if there's a way to remove the http://www.domain.com/images/ when the image (stored) name starts with http://
Here's the code from the script. I was wondering if there's a way to copy the image from the specified url and upload it to my server. Can anybody help?
// picture URL
if( intval($imgtype)==0 ) {
// URL specified
if ( strlen($sessionVars["SELL_pict_url"])==0 ) {
$TPL_pict_URL_value = $MSG_939;
} else {
$pict_url = $sessionVars["SELL_pict_url"];
$size = @getimagesize("$pict_url"); //get the actual size of the picture
$width= $size[0];
$new_width =$width;
if ($width > 400){
$new_width=400;}
if($width ==0){$TPL_pict_URL_value =$MSG_940;}
else{
$TPL_pict_URL_value = "<IMG SRC=\"".$pict_url."\" WIDTH=".$new_width.">";
}
}
} else {
// a file uploaded
if ( empty($sessionVars["SELL_pict_url"]) ) {
$TPL_pict_URL_value = $MSG_939;
} else {
$pict_url = $uploaded_path.$sessionVars["SELL_pict_url"];
$size = @getimagesize("$pict_url"); //get the actual size of the picture
$width= $size[0];
$new_width =$width;
if ($width > 400){
$new_width=400;}
$TPL_pict_URL_value = "<IMG SRC=\"".$pict_url."\" WIDTH=".$new_width.">";
}
}
