[GaroldShaffer]

OK, so I have this new avatar, look to your left. The picture on my computer looks good but of course here its a little out of focus. Ok, so I need to adjust the image size but I can't figure out how to get this info. (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)
I have the file size and was given these instructions (IMG:http://www.914world.com/bbs2/html/emoticons/type.gif)

right click on it,
then click properties,
then copy the address of the file,
then paste it in the address bar of your browser and hit enter,
now right click on the image,
then click on properties,
it will show you the image size

I do all this and it just shows me the file size but not the image size, you know like 90 x 90.... so WTF (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) I know this is simple but it is driving me nuts (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)
