Loving this little app on N95-8GB. It actually reminds me of the CoolIris plugin for Firefox. Works pretty well, but I notice it only supports .jpg format at the moment.
Do you have any plans to introduce more formats in the future? eg .PNG, .BMP and GIF, to name a few.
Personally, and I know it's mentioned elsewhere here, I think this would be a great replacement for the default image browser with the same menu functions. i.e "Send via", "Share online", "Add to print basket", "Print" and "Start slide show".

Keep up the good work, I'll enjoy watching the development of Photo Browser.
