Cant open/upload photos in the New Item Publish when this Plugin is on "Pre-resize images 1.1.1" plz see screenshoot and help.

@user77
It means there are javascrip errors caused by this plugin.
You should also enable drag & drop image uploads.

This is what the plugin instruction says to change

Setup
For this plugin to work you need to make a little modification in your theme. Find all occurrences of this line:
ItemForm::ajax_photos();

(Usually found in item-post.php and possibly item-edit.php as well)

Replace it with:

if (function_exists('przi_ajax_uploader')) przi_ajax_photos();
else ItemForm::ajax_photos();

How exactly to enable drag & drop image uploads?
It works with OsclassWizards 2.0.4, what should I change so it also works with Elena theme?

@user77
Go to theme settings and check
"Use new Drag & Drop image uploader instead old one"

 it works now, problem solved, Thanks!

@user77
Cool, welcome.
