I have some images in the header of my current development that only appear sometimes. No idea why. It may not be a Wordpress issue at all. When it’s seemingly random like this, I’m often without a clue. It may also depend on the browser. Chrome has the worst results. Safari and FF on the mac are finicky.
The images in question read, “estevan carlos benson news/faq/contact”
First thing I’d do is comment out the code in custom.js that adds all the jQuery effects to those images. Seems like a likely culprit that you can easily test.
Yeah, I did. On the first page load the images didn’t appear and on the second page load they did. Having a hard time figuring out what’s causing it like you.
