Google photos picker never appear

I finally managed to install the plugin, and I have the button in html mode. But nothing happens after I select a picture. What kind of code should I expect in the text?

After you click the select button in the dialog with some photos selected, you should be able to see code like this in post edit box.

“>” alt=”<filename>” />

“>” alt=”<filename>” />

“>” alt=”<filename>” />

I see nothing there. Where can be the problem and what to check?

Sorry to hear that. What’s your WP version?
It might be a conflict with other plugins. Can you try to disable some plugins?

you were right – conflicting plugin is this one

Any clues to make both plugins working together?

Highlighter is very useful for me
