Is this site acting "sluggish" ?

Lately I've noticed incredibly long load times for certain pages images in general. I thought it was my computer or internet, but I've tried several computers from work and home. The site doesn't want to load images. At times the thumbs will load, but not the larger images that are basic size. Just curious if anyone else has noticed this happening?

I've noticed this today. Sometimes the pages time out as well.
