Hello,
This is the error I get, when I try to upload only 1 jpeg  of about 4 MB.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 15488 bytes) in C:\xampp\htdocs\Joomla\administrator\components\com_rsgallery2\includes\img.utils.php on line 535

Please tell me what do I wrong?
Thank You,
Han

Hello Chef Groovy,
I reduced the size of my pictures! It works.
As a starter with Joomla I am working on: xampp/localhost. I have to study  PHP more, I think.
Thank You for this quick reply.
