Hello again ))
Before purchase plugin K2 Multiple Images (getk2.org/extend/extensions/763-k2-multiple-images) I would like ask a question:
What part of image plugin will place watermark? (bottom-left, bottom-right or other).

Hello this plugin was not developed by us. You need to ask this question to the plugin's developers joomcar.net/ .

Unfortunately, developer's site have not contact form or other feedback...

I am sorry but we are not affiliated with this extension, nor have I personally used it.

Hi,

It puts the watermark in the bottom right corner with no padding so you either need some padding in your image or it will be flush against the bottom. Its easy to move the position by editing the CSS.
