capturing .TIFF images at a configurable time interval and sending to a usb drive

How can I capture TIFF images from an image stream at a predetermined time interval between images, and send a copy of the image(s) to a
USB drive?
For example,I have 40,000 images per hour,each approximately 30kb each.I would like to capture a selected number for analyses of image quality issues.Alternatively, I could capture every Xth image.
Can anyone help me with this?
I am new to QNX, but have some experience in UNIX systems.

What's the source of the image stream? Will it be being displayed on an X11 desktop? Where are the files landing?

Please give a little more information and this should be an easy-ish one

Thanks for the reply.
The images are not displayed locally,but are further processed in real time by OCR software.
Displaying would create too much load on the processor and generate an intolerable time delay.
I must capture a random sample of the images for analysis without excessive loading of the processor.One image per minute will be sufficient.
I am sure it is simple for someone with in depth experience, but I really do not know how to approach this.
Your advice and guidance will be much appreciated.

The image source is a high speed gray scale scanner camera.
The images are routed to a bank of image processing computers for OCR processing via CAT6 cable, but are sent in .TIFF format.
I would like to copy a periodic sample image for image quality analyses.The images are currently not displayed on a monitor.
