Blog Button VS Me...Round 1

Grrr!  I need help! I have spent hours trying to create a blog button.  I created a jpeg with microsoft and picnik (not real cute though!) which I saved to my desktop..uploaded it to picassa web (per a tutorial), but had trouble finding the button URL.  Thought I had it, but it was a VERY strange URL...followed prompts to create code, got rid of smart quotes, added it to html widget and...no picture shows up on blog, just a code.  Not sure the code even works.  HEEELLLLPPPP!!!  Any suggestions besides beating my CPU with a sledge hammer and calling it quits?
