imagecopyresized Unable find img pointer

Anon

Who do i get the errormessage: Unable to find image pointer when i use imagecopyresized?

Is there another way to create thumbnails?

Erik

Waarom krijg ik bij de instructie imagecopyresized de foutmelding: Unable to find image pointer ?

Is er misschien een andere manier om "thumbnails" te creëren?

There is probably a bug in your code somewhere. But it's impossible to comment on if you don't provide a (short) code example of what you want to do.

Like Troels said, this could be anything.
Give us a snippet of your code and maybe we can see what's going on.

Jouw probleem kan vanalles zijn.
Als je ons een stukje van je script laat zien kunnen we misschien het probleem vinden.

Okay,

I have a jpg file uploaded by a php script. Now I want to create a thumbnail of that image file. The server has PHP version 3.0.12.

That is quite simple, but I can't help you with your code if you don't post some of it.

ImageCreatFromJPEG to open an image up and get an image identifier.
ImageSX and ImageSY to get the width and height of the image.
ImageCopyResized from copy the opened image to a new image and resize it on the fly (you need the width and height for this)
Then use ImageJPEG to save the image to disk or to output it to the browser.

I have PHP version 3.0.12 and ImageCreateFromJPEG needs PHP 3.0.16.

In that case you can either upgrade (smart move) or use an external program to do the work for you.

The problem is: (I don't know how to say it in english) PHP hosting

Anon

You said it in english :-)

Hmm I see.. well if you can't upgrade or use external programs, you're F'ed :-)
