[RESOLVED] Resizing pictures in a folder....

I have done this before, but now somethign is seriously wrong. I made a script looking something like this (shortened a bit):

Code:

---

if ($width > 500){
    $less = $width - 500;
    $prosent = 1.0 - ($less / $width);
    $new_h = round($prosent * $height);

    $thumb = imagecreatetruecolor(500,$new_h);
    imagealphablending($thumb, false);
    $source = imagecreatefromjpeg("$cfg_fullsizepics_path/$entry");
    imagecopyresampled($thumb, $source, 0, 0, 0, 0, 500, $new_h, $width, $height);
    $filename="$cfg_fullsizepics_path/$entry" . "_thumb.jpg";
    @imagejpeg($thumb, $filename);
}

---

I tested the script on all pictures in a folder where I have pictures from my phone, Visuals camera, and Mendhaks camera. But for some reason it works on pictures from my phone, Mendhaks camera, but NOT pictures from Visuals Camera. Anyone any idea. I have highlighted the line where the scripts stops. It gomes to that line when it handles a picture from Visuals camera, and then just stops there.

Any ideas? Any fallbacks I can use?
Thanks

Do you get any actual errors from the script or does it just not work?

My suggestion is check that the pth its trying to read is corrext and check that the extensions match that required by the function :)

Maybe it has somthing to do with the Header info Visuals Camera puts in the jpeg file? Maybe try and save one of them pics with an image editor and see if it still happens.

Since it works with the other pictures I can't see that the extensions should be missing or wrong version. Nor the path.

Hmm... it is an interesting problem.

Any chance you can post a link tothe page?

Are you shure its that line?

Try removing the "@" infront of the imagejpegfunction and see if it returns anything that may be of use, also did it generate and rror log to say somethiin was wrong?

I think I found the problem now.


- Did as AWC_Joe said. Opened it up took the pen and drew some nice stuff on it and saved it again. Still didn't work.

- Opened it up, resized it from 1600x1200 ->1024x768. Then it worked :sick:

- Opened it up, resized it from 1024x768 -> 1600x1200. Then it didn't work...:(


SO guess there is some size limit here somewhere..:( Not sure where though...

When I think about this....Isn't 16Mb it says there? Am I not freeing up memory somewhere? Maybe that is the reason? Or is the image just too big?

And once again, VisualAD helped me on way. I just changed the amount of memory my script is allowed to use. So now it works..:)


i.e:

PHP Code:

---

ini_set("memory_limit", "32M");
