[Plugin: Picasa Widget] Changing the url?

Hello everybody,

I have a question and i do not know anything about PHP but just a bit of html-/css.
I was building a site with WordPress and i need to make a photo gallery-page but because of the space limit we have on our hosting-/servers i thought it was a great idea to load the pictures into a Picasa-album (google).
Now i also have a single page on my WordPress site that is called “Photo’s” here is where i want to include the pictures from the picasa album and show them so users don’t have to leave the site to view pictures I think that can be done with a WordPress -plugin.

But now i have this Picasa widget that i want to use on the sidebar of my theme and it works perfect the only thing i want is when i click on the picture in the sidebar it moves me to my picasa-album url (picasaweb.google… blablabla) is it possible that i can change the url to my Photo’s page on my site?

I don’t wanna be lazy, i’ve seen something that was called:
fetch_rss("https://picasaweb.google.com/data/feed/base/user/".$options['username'].

Is that what i need to change? i don’t know because the rss doesn’t sounds like a a href tag.
So if somebody can help me thanks.
