Stop laughing! I did the same mistake of underestimating the use of a border. If so, please tell me which you prefer of the two photos:
Both images are exactly the same, except for the border. Convinced? Lets start!
- Open your image in Paint.NET or GIMP.
- To add the first border (I used a white one, please use simple colours/gradients):
- In Paint.NET go to Effects>Render>Borders N' Shapes (if you don't have this plugin installed go to Image>Canvas Size... and increase the size of approximately 120% and remember to center the image. Then choose the rectangle, adjust the pixel width (in the top left) to about 10px (depends on picture size) and use it to create a border.
- In GIMP go to Image>Canvas Size... and increase the canvas size. Check the preview and don't forget to center the image by pressing Center. Go to Select>All to select the image and then go to Edit>Stroke Selection... Choose width (around 10px) and press Stroke.
- Add the second border:
- In Paint.NET use the fill tool to fill the appropriate colour. Remember to set the Tolerance Level (upper center) very low, about 1-3%.
- In GIMP go to Layer>Transparency>Add Alpha Channel and go to the layers palette and add a new layer. Fill the new layer with the wanted colour.
- Add some text:
- In Paint.NET create a new layer and choose the Text tool. Add the text and position it using the Marquee Tool. An alternative way is to use the Center Object plugin.
- In GIMP use the Text tool to add text and reposition it.
