Warning: imagejpeg() unable to open for writing

sem_db

I recieve this error message on UNIX but not on Windows.

I am attempting to use the imagejpeg() function in the following manner:

imagejpeg($new_image, $new_location.$file_name);

Any help would be greatly appreciated🙂

'Cause Windows doesn't know &*( about permissions? 😉

Seriously, check the permissions for the directory in question. Is it /tmp? It'll need to have permissions set for whatever user PHP thinks it is....

Thank you for the advice. I store my thumbnails in directories corresponding the their size, and have set user and group permissions to write as follows:

drwxrwxr-x 3 emdb www 4608 Feb 25 15:11 lrg625
drwxrwxr-x 3 emdb www 4096 Feb 25 15:11 med310
drwxrwxr-x 3 emdb www 4096 Feb 25 15:11 sml200
drwxrwxr-x 4 emdb www 4608 Mar 24 15:45 xlrg1250
drwxrwxrwx 3 emdb www 4608 Mar 14 17:50 xsml50

Yet,
I'm still getting the error:

Warning: imagejpeg() [function.imagejpeg]: Unable to open 'http://bi.math.ubc.ca/cellbiol/media/images/xsml50/1049444211_F1330016_257x384_818510_-1.JPG' for writing in /includes/Image.php on line 179

Is there a temporary directory somwhere that I should be aware of?

Is your web server Apache? What is the name of the Apache user (nobody, www, daemon....) To what group is the daemon assigned?

Your permissions show only one dir that is writeable by anyone. If Apache is NOT running as user emdb or some other member of group www, I should expect that your function would only be able to write to the xsml50 dir.

But it says it can't write to that one either.......

Hey! Hold the phone....you've got your image location set to an [url]http://[/url] protocol URL!! Try writing directly to the server....

and i receive this message on windows.....
how to fix that?

And one other thing, probably unrelated, but good to know perhaps. There are a few FTP clients (notable the Windows CLI client) that insist on CAPITALIZING filename extensions during the transfer. So, you end up with "file.JPG" instead of "file.jpg" on your server; since UNIX cares about upper/lower case, you end up "not finding" said files...

OTOH, I doubt it's relevant here, but I dunno....

Milenius, I suspect you'll need to post your code, or at least give more details....

Thank you for your attention! I fixed the problem using the suggesstion above (ie "hold the phone"). I was using an incorrect path name for the image. Thanks again!

I'm trying to create jpeg picture pixel by pixel. Here's the part of code I am using:

$image=imagecreatetruecolor($hori,$vert);
for ($i=1;$i<=$vert;$i++)
{
for ($j=1;$j<=$hori;$j++)
{
imagesetpixel($image,$hori-1,$vert-1,$color);
}
}
imagejpeg($image,"map.jpg",100);
imagedestroy($image);
print "<img src=map.jpg>";

im getting error like this:
Warning: imagejpeg(): Unable to open 'map.jpg' for writing in C:\Inetpub\wwwroot\map\index.php on line

im using Windows XP with PHP 4.3.2 on IIS included with windows.
phpinfo() says that GD is working (bundled 2.0.12 compatible) and jpeg support is enabled. Not sure what other info might be useful to solve my problem.
thanx for helpin me out.
