createimagefromjpeg with URL parameters fails

[whirlpool6]

hello everyone.

i have installed gd2 on our linux server and used createimagefromjpeg with a URL parameter. this fails and returns an empty string. i tried to access a native public url but it doesn't work as well.. when i changed the native url to the ip address of the server, it works perfectly.

i don't know if i missed something but i really have no more idea how and why this happened...

can somebody please help me.

thanks a lot.

Hello and Welcome to WebmasterWorld!

Make sure your allow_url_fopen [us2.php.net] directive is set to true otherwise it will not correctly work.

[whirlpool6]

yes allow_url_fopen is turned on. is there something else i missed?

[eelixduppy]

Aside from the fact that you are using the wrong function (assuming you are using what you have wrote in your first msg). The function you should be using is imagecreatefromjpeg [us2.php.net] not createimagefromjpeg.

I don't see any other reasons why it shouldn't be working. Maybe safe mode has some affect on it in which case you may want to check that out.

[whirlpool6]

hey sorry for that... it should have been imagecreatefromjpeg... i just wrote it wrongly but i used the function correctly.

what is safe mode? our servers are all apache in linux. how would i check on this?

[whirlpool6]

the previous entry was somewhat erroneous. here is the real deal guys.

i cant access images in php... here is the warning it shows.

Warning: imagecreatefromjpeg(http://trialhost:81/DOCUMENTUM//430/ss007-2007052634012.jpg) [function.imagecreatefromjpeg]: failed to open stream: HTTP request failed! HTTP/1.1 401 Access Denied in /usr/local/apache2/htdocs/iv_stage_fritz/try.php on line 8

i dont know what is with the access denied... i have to make sure first that this is not with the configuration before i ask the sysad...

pls help.

Did you try removing :81? Do you try to access jpg located on the another machine from your network? Maybe image permissions on that machine does not allow to view?

[whirlpool6]

but i can access the image in browser...

if i remove 81, nothing can be seen... a specified port must be written.

[eelixduppy]

This is safe mode: [php.net...] Make sure that it is disabled.

[whirlpool6]

yup allow_url_fopen is turned on... im using urls because the images come from a different server...

[whirlpool6]

yes i have checked and it is not in safe mode...

what version of php do you have?

also you could be getting blocked from the other site.

[whirlpool6]

im using php5. i have already informed the other party but still we are waiting for reply. but ive got to make sure that it really is not a problem on our side. what other configurations do i have to check?

thanks a lot..

[jatar_k]

because it is returning a 401 my first look would be why the other server is denying the request.

Have they setup a username/password?

[whirlpool6]

is it possible to setup username and password on specific addresses only? like if 12.12.12.12 accessses, no authentication is required and if 10.10.10.10, needs an authentication?

the other server i think is running on iis.
