Apparently regular html doesn't work for the sigs...how do I center it without the
< center> marks showing? Also, I have it set to the guidelines but it looks a lot smaller then everyone elses...any ideas on that one?

Well 200 x 100 is indeed small for a signature. usually the width is about 300-450.
and you just use the centered sign on the right.

Guess I was trying to make it to complicated with the centering, lol. Now for the size...in PS I have it set to the guidelines...but it's coming up a lot smaller. I have it 500 x 250 so why did it change?

Because thats to big. stay in this range.

Width 300-400
Height 100-150

Could it have to do with me uploading it from my computer? I uploaded it to photobucket but I can't use the links yet so that didn't work either. I resized it and it still did nothing...

if your uploading it to this site then it should automatically resize it to 400X 150 i think it is

I am uploading but it is sizing it to 199 X 100

Looks a little bigger now....

nope, its 350 x 100.

If you used photo shop scale it to the size you want, then re-upload it to photobucket, then upload it here again. It links the numbers when it resizes I'm pretty sure.

Here is another question...How do you alter the file size so that it doesn't exceed blizz's requirements? I stayed in the pixel guidelines but now I'm over the file size.

If its a still file I don't know how your exceeding the limit. Most of my sigs are animated and they never went over the limit.

I fixed it. I was saving as a png -- saved as a jpeg it makes it a lot smaller in size.
