1. Rounded Corners: There is something about Rounded corners which make Photos look very cool. So here's how you can give your photos rounded corners:
Now select the 'Rectangle Select Tool'. It is in the GIMP Tools window. Now select entire image or the part of the image you want to round off. Now go to menu Select > Rounded Rectangle.... A box would pop up asking you to specify the radius in percentage. 50 is the default value. I'd recommend something like 15-20.
Next right click on the image and go to 'Select' in the menu and then click on 'Invert'. Now hit the delete button. Now hit Ctrl+S to save your creation. Here is an example.
Now this is VERY important. After selecting the proper image part, you should right click on the image and click on 'Select' in the right contextual menu. Now click on the 'Invert' in the sub menu. Now hit delete button on your keyboard. Cool, You have successfully kicked out the dog! But still there is the ugly white space around the part the dog once existed. So go to the menu, Image > Autocrop Image. This will get rid of the white space.
simply use the Crop Tool from the Tools, it is above the 'Text Tool' it can do the work in a better way.
6. Adding text
Use the text tool to add some text. You will get a new text layer which you can also see if you look at the layers dialog. You can use the move tool to move the text where you like to have it. Then merge it with the white layer below by choosing Merge Down from the Layer menu. You should now have one layer with black text on white background. Using Layer -> Colors -> Invert you will achieve something like the picture above.
