Using GMAIL to host files

Ok, i know that you can do this, and I have done in the past; theres a few standalone program's as well as firefox plugin's to do it..

However I have a question:
Last time I used this to store images, which I later refered to on another website, they did not display. It worked out you had to be logged into gmail, for the images to display... Is there anyway around this?

...Basically I just want to use it like imageshack or something like that, to host my images, which I can link to..

Help appreciated
