Problems with uploading

First it was trouble getting connected to BT Yahoo, I have to do it via FireFox.
Now it is problems uploading to Morguefile, although i can upload to Flickr with no bother.
Morguefile is a very good website devoted to royalty free pix for any-ones use. No restriction EXCEPT they cannot be used as a free standing pic for sale. Although there are some people that download them and create posters etc
