Hello group please suggest me how to add/remove the frame surrounding the image?

Thank you all for the suggestions!

Can you upload a file, sans any private content?

Hi,

It seems that this is the border of the anchored frame. The dotted line inside of this black frame is the border of the graphics which you had imported.

Open the Anchored Frame pod to check this.

You can remove this black line with the Graphics toolbar (View | Toolbars | Graphics Toolbar).

Select the anchored frame.

Then click the small arrow to the right of the "Set Pen Pattern" icon (see screenshot; this is the 10th icon from top; in the screenshot ).

Then click "Pattern None" (lower right icon).

You can experiment also with the other icons, just to check that you had selected the correct frame.

The icons do not show the current state, but what you want to do.

In case this is really something different like a text frame border (which I do not believe), select this border, right-click to open the context menu and select Object Properties. Then select Stroke and select another pen pattern and click Apply.

Best regards, Winfried
