How can a JPEG be an application?

When I try to open certain photos I copied from web sites, I get the warning: XYZ is an application which was downloaded from the Internet. +Are you sure you want to open it+? An Apple support page says to use Get Info to check the file's kind. I do so, and it says "JPEG image", just like other JPEGs that do not display the warning (Leopard 10.5.6). What are these things? When scanned with Norton on my PC, they are pronounced spyware-free--but the PC won't display them either. They were displayed fine in Firefox when I enlarged then on the web page, and I saved them just like I save anything else (R click, Save Image As).

? Thanks for any help. I assume I should delete these things.

UPDATE--I noticed the same pics can be saved using Safari rather than Firefox, and the problem disappears. Also, the pics can be saved from my PC (with Firefox) and transferred to the Mac and they are fine. When I do have the problem (only certain pics; Mac + Firefox), the file size is always 16 KB, no matter the size of the original file.

it's typical. The OS is just issuing a friendly warning. Don't think
there's a way to disable it.

Thanks.

There actually is a way to disable it, I have read, but I don't want to. The concept is good. My question is why does a file saved with FF get flagged but the same file saved with Safari does not? And in fact, most JPEGs saved with FF work fine....

This is irritating, because I like FF better than Safari (NoScript, WOT, other add-ons are great), and I can't tell when I am saving a JPEG if it is going to be rejected by Leopard until I try to open it later.

-Hi,

As you know: Browsers are NOT created equal and FF might be flagging it due to the site you are snagging the .jpg pixs from. I've used FF for years and never seen that message. FF v3.0.5 presently. :::guessing only:::

Re: How can a JPEG be an application?

Thanks dougster.

I sort of figured it out. The only time it seems to happen is when there is a separate View and Download option for a picture. If I click on the pic or click View to enlarge the pic, and then R click > Save image as, the resulting file is unreadable, as described earler (except with Safari, when it is fine....). When I am using Firefox, I have to use the Download button. Then it saves normally. I'm not clear on the difference between Save image as & Download image, but FF does make a distinction wih certain images. And then there is the question of why the Mac thinks it's an application.....

I am running FF 3.0.5 as well.

Hi -N,

I use a single click Apple mousie and use Control + Click on the image-->Save As...that way I change the name of the pix. Not sure that makes any difference at all. And I'm still not sure why the app message poPs up. Very odd...
