Thanks.... Just to understand.   I should save the file as an afphoto or jpg;;;; and then use the .... how can I replace the image that is currently thee without pasting or dragging and dropping?

Is the image that's currently there Linked or Embedded? Is it a (Pixel) layer or an (Image) layer?

If you click on it, do you have a Replace Image button in the Context Toolbar?

Hi @Zulu,
Welcome to Affinity Forums
Switch to the Move Tool, click the Image or Embedded Document (the process is similar in both cases) on canvas (or select them in the Layers panel) then go to the context toolbar and press the Replace Image or Replace Document buttons. You can identify the type of layer you are working with looking at the label between parenthesis after the layer's name in the Layers panel.
Complex document with multiple objects (PSD, SVG etc) are placed as embedded document layers (or linked layers if you sett document to use linked) whereas raster images (TIFF, PNG, JPG, etc) are placed as Image layers.
