When resize = true, the upload is too slow about class.upload.php HOT 9 CLOSED

I am afraid that there is no easy solution. Either your machine is too slow, or has limited memory, either the image is too big. If you are looking into processing large images, you should look into imagemagick which is faster than GD2.

That's weird. Online it happen too, with simple images, but ok.

Care to share the log produced by the class?

1920x400 is unfortunately a fairly large size, and it may explain why the processing is slow. What matters is size in pixels, and that increases exponentially with larger image dimensions. Besides resizing, your process is also a conversion to JPEG, so the class has to fill transparent areas with a background color.
So to me, it looks fairly normal that it may be slow.

from class.upload.php.

there's a way to no use the conversion process? Becouse i'm already uploading a jpg file

from class.upload.php.

Not really... But you seem to upload a 1920x400, to get in the end a 1920x400 image. Is that normal? If you have the right resolution from the start, no need to resize obviously...

from class.upload.php.

You know... sometimes the users don't read de advice: "PLEASE, UPLOAD A 1920X400 PIXELS IMAGE" ahahah
Fine man, i'll do something. Your class is awesome, too easy to use and so many resource. Thank you for all
