Thank you for your replies!
I thought about this after posting, and obviously it would help to post something.
So, I have some updates:
I have uploaded them (the jpegs) to Photobucket just to check if it is a bandwidth issue, but only one image was fixed; one I created using Photoshop, a simple quote on a white background. However, the three images that will not work were sent from the client. The .jpg extension is also in capitals on the files for some reason?
I can not post a link due to privacy issues with the client, but I would be able to tell you that I am simply using
HTML:
<img src="http://imgurlhere.com/image.JPG" />
?
Anymore information I can give?
I have a Mac Book Pro that runs a Parallels Desktop with Windows XP installed. Esentially I have two computers one. If you provide a URL I could take a look. Off hand it seems weird that the JPG files only show up in Safari? Have you tried resetting Safari, emptying the cache? Maybe the only reason you are seeing it in Safari is because the images are cached? I am shooting in the dark here, a link would be helpful.
I also have a MacBook Pro with Parallels Desktop, and Windows XP installed. That is where I checked the images, on Internet Explorer, as opposed to Safari, and no luck there! I also checked them on other machines: no luck!
AHH, please help!
