copying and pasting

I am running Comodo V3. I use a photo storing site on the web and find I cannot now download those pics I have uploaded. I use them in a graphics site to which I belong. It seems that I can copy them from my storage site (photobucket) but cannot paste them into my graphics section. It seems that comodo is blocking them somehow.
I can copy from photobucket and when i try to paste into Word, Comodo asks me if I want to do this. Unfortunately I do not even get the paste command showing when I try to put them into my graphics section on the web.
Any ideas.
I am running winxp pro
