Using your PSPIMAGE as a corner accent.

OK... you've done a wonderful frame and you are ready to add your premade corner to it. For simplicity of explanation and viewing I made a very simple frame with a wide outside border.  You can grab it here.

Open your corner tube and select the colored layer that matches your frame.
Hide the others in the layer palette.

Edit > Copy

Click back on your framed image.
Edit > Paste as New Layer

Use the mover tool to drag your corner where you want it. I put mine in the upper right corner slightly over the top of the darker frame.

Make sure your corner layer is highlighted in your layer palette.
Layers > Duplicate

Altho it looks like nothing happened, you will see a new layer highlighted in your palette. It will be called Copy of Raster 2.

Image > Flip.
Magically, PSP reads the first layer position and places it in the right place! Now you will have the upper two corners done in your frame.

Hide the background layer by clicking on the eye behind Background.

Right click on Copy of Raster layer and choose Merge > Merge Visible

Duplicate the merged layer (Layers > Duplicate)

Image > Flip

Merge the visible layers again so that all four corners are on one layer.

Unhide your background layer.

Add a subtle dropshadow to your corner layer.

Corners in a frame should not have a directional drop shadow that indicates a strong light source.

Add a new layer with your watermark or signature.

Layers > Merge All (Flatten)

Export your frame as a jpg with a compression setting of 8.

File > Export > Jpg optimizer.
Compression Value of 8
Click OK.

Next Screen - Give your file a name and select where you want to save it.
