[SOLVED] Getting a blank header image...sometinmes, after installing 3.7.17

Here is one site: http://bellamylearningcentre.com where the header does not load. It will occasionally if I refresh. But If I right click the white space and ask to view the image, it tells me "The image "http://bellamylearningcentre.com/wp-content/ata-images/header/bellamy-learning.jpgLCK" cannot be displayed because it contains errors.

I re did the graphic, called it something else and uploaded and removed the old one. Same problem.

i can find nothing on .jpgLCK but if I look at the image on the sever, the extension is .jpg only
