There are two issues in this record.
Errors occur when opening TIFF or JPEG images in Photoshop:
"Unexpected end of file occurred" when opening TIFFs.
"Could not open because an unknown or invalid jpeg marker type is found", when opening JPEGs
Re-create the image in the original application, making sure that the extension is appropriate for the File Format.
Save the images to the hard drive, then copy them to the removable media.
; Save the image as JPEG or TIFF from another application.
We have found that some of these images are saved with an extension that doesn't match the file format. The file format attached to the image must be appropriate for the actual file format in which you are saving the image. If you change the filename extension (.jpg or .tif) and you don't resave the image as that format, you might not be able to reopen the image.
We have also found that these errors can occur when images are written or saved directly to a removable media. Saving the image the hard drive first, then using a copy command to copy the images to the removable media makes it less likely that your images will be damaged as they are written to the removable media. You might also have a damaged cartridge or diskette.
The application writing the image might be saving it incorrectly. Save the image with no compression (if you are saving a TIFF), and see if Photoshop can open that image. Or Save the image in another application.
The image might simply be damaged. Rescan and resave it to a new name.
Some new ideas from the forum:
NOTE: these solutions are untested by support, they are just suggestions of how to get images to open in emergency:
If you can't reopen your JPEGs try:
* remove and reinstall Photoshop (unlikely to help)
* delete/reset prefs
* save as PSD (always archive your images as PSD, not as JPEG, especially if you reopen the images)
* if there's an update of Photoshop, install it
* make sure there's plenty of hard disk space available for temporary files
* use Open As
* open the JPEG in Internet Explorer and re save it out - it flattens the file, though
* make sure that the image has the appropriate extension to the actual file type (use Get Info to get the file type)
* try opening the image in another application, such as Graphic Converter

Reported that resizing images and saving as JPG can cause the same error.
When resizing files with Crop tool and "Image Size" menu:
- make sure to use the crop tool first before resizing in the Image size menu.
Appears that the order of the operation can cause error on opening the file.
: "Could not load color setting because of an unexpected end-of-file. Using default color settings."
The OK on the error message box is dimmed.
The Color Setting preference file is damaged. Delete it and restart Photoshop. Also, check the hard drive for further corruption using Scandisk and Defragmenter or, if you have a SCSI hard disk, a SCSI utility.
From original - do not delete:
These images were created on a Windows NT machine, thentransfered via removable Zip to a Mac
Some of the files on the zip open all of the time, and theremainder never open, on either the Win or Mac machine.
The original files that were saved to the HD of the Windowsmachine are fine, however.
Res: The problematic files have been corrupted on the zip.

Mark replied to a customer on the U2U forum who gets the error message with jpeg files mailed to him. That reminded me that i once dealt with a customer who had the same problem. Unfortunately, I trashed lots of collected e-mails before I moved here and that seems to have been one of them.
The error message means the jpeg marker has not been created properly by whatever application was used. You can easily reproduce the invalid jpeg marker message by saving a file as DCS 2.0 and then overwriting the .eps file ending of the composite file to .jpg on the Mac. Go to the File>OPen dialog box in PShop. Note that the file type of the composite file is now listed as jepg! Of course it's not a jpg since only the filename was overwritten.This file will not open any longer in PShop and throws above error message. The U2U customer should get in touch with whoever creates the jpegs to ask how it was done. Most likely, the person who created the file did not use the application properly to save the jpeg but "fiddled" around with it himself afterwards like I've just done.
