"In-camera" JPG Files Treated Differently Than "On-disk" JPG Files

When I hooked up my wife's digital camera to my Win7
computer, I decided to look at some of the photos before
copying any to the Hard Drive.

I use IrfanView to look at images on this machine, but when
I dbl-clicked one of the camera's JPG files, the Windows,
built-in app (Windows Image Editor?) came up and displayed
the photo. I close it, and looked again in Windows
Explorer. All the photos showed as "IrfanView" files. I
right-clicked on one, thinking that I would select "Open
with", but there was no such offering on the popup menu!

Does anybody here know why this would be happening?

If I am reading this right, you are connecting the camera to the computer
(with a USB lead?)

I wouldn't have thought that would be any different to putting the card into
a USB adapter or built in card reader which is what I do now.

I have two applications on my machine (Paint Shop Pro and Ashampoo Photo
Optimiser) in addition to Windows Photo Viewer which is the default
application provided with Win 7.

If I slip the camera card into the reader and click on Open Folder to View
Files in the pop-up window. I see a list of all the images (I have the view
setting as Details rather than Icons), with the file type shown as JPEG
image.

Double clicking on a file opens it up in Windows Photo Viewer.

Right clicking on a file brings up the usual menu of about 14 options,
including "Open With Ashampoo Photo Optimiser" at the top and "Properties"
at the bottom. Somewhere in the middle there is an "Open With" option, which
when clicked offers just two items, Windows Photo Viewer and Windows Paint.
Paint Shop Pro does not appear as an option.

I can add Paint Shop Pro as an option (and set it as the default option if I
wish) by choosing "Other" from the Open With menu, and then browsing to the
folder in the file system containing the executable, and selecting it.

If I do this then double clicking on the image list will open up the file in
PSP.

However next time I right click on an image file Ashampoo Photo Optimiser
has disappeared from the list of options for opening the file - Strange!

If "Open With" is not on your right click menu, you could click on
Properties, and will probably see that the file is set to open with Windows
Photo Viewer. There should be a "Change" button on Properties pop-up, where
I believe you can change the application which opens the file. Whether this
is per file or for all files of this type I do not know.

Beware of rotating the images in Windows Photo Viewer if you are using it to
see what is on the camera card. My Wife did that and moved on to view the
next image. It seems that the viewer does not prompt to save/discard the
changes. She found that next time she previewed the images on the camera
screen any that she had rotated on the computer were no longer recognised by
the camera - Error Invalid Image.

Yup.

Me, neither.

When I right-click on an in-camera JPG and click
"Properties", it shows that it "opens with IrfanView", but
if I dbl-click on it, it opens with Windows Photo Viewer! If
I do the same with an on-disk (HDD) JPG, it opens with
IrfanView.

I assume that you installed the software supplied with the camera when
you bought it. Perhaps when you plug the camera in (via US8) that
software recognises the camera and automatically selects the Windows
image viewer.

If the camera software starts when you logon, try disabling it
temporarily. Then plug the camera in. If your computer can still see
the camera's memory, see what happens when you click on a *.jpg file
name. Does IrfanView open it?

File associations and icons used are separate things; they don't always
go together. It's very possible to have an Irfanview icon used for a
file type which opens with a different program. It all depends on the
history of which programs have swapped and changed their associations.

Unless you're using some third-party program to view the files in the
camera when it's connected through USB, then W7 will use its standard
list of file associations.

Go to Control Panel/ Programs/ Default Programs/ Associate a file type
.... and list them out. Note which programs are assigned to these three
types;.jpe, .jpeg and .jp2

Plus, of course, .jpg.

Nope. Wife's camera--my computer. Windows 7 provided
whatever driver/interface was needed without asking me for
anything. Canon site offers nothing for drivers for this
camera (A1100is)--says Windows will handle it.

No Canon software installed.

Nope--Windows Image Viewer--even tho Windows Explorer shows
them as Irfanview files!

If I right-click on a JPG file, whether on the HDD or on the
SD Card while in the camera (thru the camera's USB cable),
Windows Explorer says "Opens with Irfanview". If I
dbl-click on one in the camera, it opens with Windows Image
Viewer. If I dbl-click one on my HDD, it opens with
Irfanview.
