Fatal error: Uncaught Error: Call to undefined function imagecreatefromjpeg()

Just starting a new thread on this as I was more than beginning to hijack the other thread!

I'm getting this error when I attempt to upload an image via MySQLi Insert Record and File Manipulation Upload Wizard:

Fatal error: Uncaught Error: Call to undefined function imagecreatefromjpeg() in C:\inetpub\wwwroot\tammyssweetstems\webassist\file_manipulation\helperphp.php:962 Stack trace: #0 C:\inetpub\wwwroot\tammyssweetstems\webassist\file_manipulation\helperphp.php(174): WA_DFP_ResizeImage() #1 C:\inetpub\wwwroot\tammyssweetstems\njadmin\add_banner.php(78): WA_DFP_UploadFiles() #2 {main} thrown in C:\inetpub\wwwroot\tammyssweetstems\webassist\file_manipulation\helperphp.php on line 962

Is this definitely related to not having GD installed in PHP?

I have checked some support sites and I don't have php_gd2.dll installed in the ext directory of my PHP install directory, nor is php_gd2.dll referenced in my php.ini file. It simply references php_gd.dll (which may well be a change of refernce in PHP8, I don't know)?

I just wanted to double check that it's not related to the helperphp.php file, which is referenced in the error that's displayed.

Line 962 helperphp.php is:
$src = imagecreatefromjpeg($imageFilePath);

Line 174 helperphp.php is:
$resizeResult = WA_DFP_ResizeImage($tmpFileNamePath, $val);

and Line 78 add_banner.php is:
WA_DFP_UploadFiles("WA_UploadResult1", "NJbannerIMG", "2", "[NewFileName]_[Increment]", "true", $WA_UploadResult1_Params);

The issue is that GD library is not installed on your php server. It doesn't appear to be an issue with the php code itself, this is a server configuration issue.

I followed the instructions detailed here:
http://www.webassist.com/community/tutorials/view_tutorial.php?tutorial=Enabling-the-GD-library-setting

...it did not resolve the issue.

I have PHP8 installed on Windows 10 and there is no php_gd2.dll in the ext folder, yet it is referenced in the php.ini.
So, I copied php_gd2.dll from an earlier version of PHP and dropped it into to the PHP ext directory.

I stopped and restarted IIS, to no avail, and when I check http://localhost/phpinfo.php, it does not show any settings for GD, suggesting that it is not installed.

So, considering that the php.ini file references php_gd2.dll yet in the ext directory of the PHP folder it only has php_gd.dll, I edited the php.ini file to reference, instead, php_gd.dll and when I run http://localhost/phpinfo.php it now shows GD info and the WebAssist extension is back working again!

I can only assume that this is an error with installation of PHP8. It's referencing php_gd2.dll when in actual fact the file, in PHP8, is php_gd.dll.

However, I fear my troubles are not over yet as I'm now getting this...

C:\>php -v
PHP Warning:  PHP Startup: Unable to load dynamic library 'php_xmlrpc.dll' (tried: C:\Program Files\PHP\v8.0\ext\php_xmlrpc.dll (The specified module could not be found), C:\Program Files\PHP\v8.0\ext\php_php_xmlrpc.dll.dll (The specified module could not be found)) in Unknown on line 0
PHP 8.0.0 (cli) (built: Nov 24 2020 22:02:58) ( NTS Visual C++ 2019 x64 )

THere is no php_xmlrpc.dll in the ext directory of the PHP8 install.

Teething problems with PHP8? Should I be reporting this kind of thing?

Thank you.

Server configuration isn't my expertise. You might want to find an IIS forum to ask questions on to resolve issues with your server configuration.
