new forum user having problems seeing pics! help!

[schwartz]

hello all,new to this board. I am registered and logged in, and read all the FAQ's, but there are some pics I can see that just simply "show up" as I look around,and others that show a tiny box with a "x" in it where a pic is supposed to show up.when I click on the box, a pic still does not appear. what am I doing wrong?
