Suddenly I remembered an interesting feature on Picasa -- a free program from Google which lets you organize and edit your pictures. You can select a folder of pictures and make various different collages of them. I copied and pasted a few of my "China" photos into a single folder and clicked the "create collage" button. Here is what I got:
After this, I made some space in the centre of the collage by manually moving the pictures around with my mouse. In this space I added my blog name and saved it as an image file. All of this could still be done using the Picasa software -- easy.
This was only the first try, when I have time after work I will play around with it a little more. Let me know what you think about the new look.
