Sounds like you got a Picture CD, which contains JPG files that
are 1536x1024 pixels (from 35mm) and 1536x864 pixels (from Advanced
Photo System film). Each Picture CD can hold images from only one
roll of film, partly because each CD also contains imaging software.
Photo CDs on the other hand can hold images from many rolls of
film, basically limited only by what fits on the CD. This is
usually over 100 images, or about 5 rolls of film. Each PhotoCD
contain PCD files which have five copies of each image at
resolutions ranging from 192x128 to 3072x2048 pixels. If you use
IrfanView to view PCD images, it defaults to showing the 768 x 512
pixel version.
To show either of the largest two image sizes (1536x1024 or
3072x2048) you have to download and install the PhotoCD plugin.
There's also a Pro Photo CD designed that's really designed for
images from MF roll film and 4x5 sheets which adds a sixth
resolution image of 6144x4096 pixels. IrfanView doesn't have an
option to display these 24mp images.
