Hi, I have had some great help here creating a picture upload form with automatic resize, But I have come accross a problem - it does not seem to like huge pictures.
Here is the previous thread:
http://www.experts-exchange.com/Web/Web_Languages/PHP/Q_21521973.htmlWhen I was testing earlier I was only using 800x600 pics to test it, but now I am trying pictures that are about 1.5Mb + and a much higher res and I am getting this error:
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 7768 bytes) in /home/httpd/vhosts/cloverl
eaf4.co.uk
/httpdocs/
upload.php
on line 76
Also when I tried a 2.4Mb picture I got the error message that was built in to the code: There was an error uploading the file, please try again!
Any ideas? I have adapted the code slightly, nothing major - just the text that users see, heres the latest:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "
http://www.w3.org/TR/html4/loose.dtd">
