Thanks for your question. First, let me request that if any of the
following is unclear or if you require any further research please
dont hesitate to ask me for a clarification.
You requested a source for high-resolution images of flags 300 dpi,
9 x 12.
Here are several options, but please note that 9 x 12 does not
appear to be a standard size typically, you will find 8 x 10
(photo format) or 8.5 x 11 which fits standard A4 printer paper.
You can easily scale the images to 9 x 12 size if that is absolutely
the size you need without losing much in the way of noticeable
First, you can purchase flag collections from Fotosearch. Their
images are 300 dpi 8x10 and the collections are $239.95 each; they
are produced by Comstock.
You can also purchase larger 300 dpi images, 8 x 12 for $209.95 each
a bit pricey.
Stockbyte produces several collections of flags that are also 300dpi
and 8 x 12
These collections are $299.95, and each collection basically includes
all of one continents flags.
Eyewires collection of world flags is not complete; however, it does
include 98 300 dpi images that are 8.5 x 11 each and the collection
sells for $289.95
Finally, there is a collection from Imagesource that includes smaller
300 dpi images, but they are only 5 x 7. This one collection does
include 325 images (sounds like most of the worlds flags) for $399
If you would like to sacrifice quality, you can access every single
flag from every nation in the world at
The images here, however, are low res about 3k for a 300x200 pixel
.gif (but they are free, although if you are seeking these for
commercial use you will have to negotiate for permissions).
I hope this response adequately addresses your request. Please let me
know if you are in need of additional information concerning this
