Round corners on picture disappearing after switching slide

Hey there, for my website i am trying this javascript slider and i must say its better than i've seen so far. i got to a point though where i can't seem to fix a problem with just CSS.First of all, what i want: I want my menu on the left, my picture on the right and using border-radius i fixed round corners on every side.Now the problem is, these round corners disappear when switching slides. the border radius is still there but the picture gets on top of it. As soon as it switches slide again the round corner is back for a second though. Like this is where it refreshes.Is it possible in any way to have the slider refresh this CSS right after it loaded a new image? like loadimage(); refreshcss(); (commands completely made up for the matter of giving you an idea what i mean)oh btw how i fixed my round corners, may it be of any use : #slider {    float:right;    width:680px;height:306px;/* Make it the same size as your images. */ background:#fff url(loading.gif) no-repeat 50% 50%; position:relative; margin:0 auto;/*make the image slider center-aligned */ overflow: hidden; border-top-right-radius: 10px; border-bottom-right-radius: 10px; }(notice the last 3 lines) :)May any of you know a solution to this, if its my idea put to use or not you would really help me out!Thanks in advance!
