I don't think I'm the only one still using Internet Explorer, am I?
That graphic is huge and slows down loading.
The GFS claims the West Coast of FL should watch out for this sometime overnight on Friday/Saturday.

The size of the image by its dimensions has nothing to do with how long it takes to load. Filesize (bytes) is what affects that. If I resized it and halved the dimensions, say taking it from 800x600 to 400x300, the filesize remains the same -- say at 800,000 bytes. For instance, I could link an image that is 100x100 that is 1,200,000 bytes that would load MUCH slower than an image that is 1200x1200 and 350,000 bytes.
