unsecure items, logo, HELP

[kitcorsa]

i have added a logo to my foot on my sites www.fire2you.co.uk and www.rubberduckbathrooms.co.uk as in my siggy.

the logo is stored on the server in the image folder and is a gif file. once i now start to go into the site and log in i get a pop up saying some items are not secure, and its the logo.

how can i sort this out?? ive noticed since ive added this logo my sales have dropped.

solved, i was silly and had the image direct linked instead of open linked lol

ie http..... instead of ./
