Jaqui,
I was specifying that there are minimum sizes to be considered for full page. It's simply a requirement in order to have the quality enough to blow the image up to a full page of print. Low resolution images will look pixelated (blocky). If you camera can take pictures that are at about 4 megapixels or larger, then the original image from your camera can qualify for consideration as a full page shot (see examples of previous years how I use images for various positioning and sizing).
So, people should send me the original quality and resolution of images as they come out of the camera. If they meet minimum size requirements I can/will consider them for the larger positions in the layout. I took a quick look at what you emailed in... they are at the minimum size for full page consideration (just slightly over the 2200 x 1700 appx. minimum). The main concern I see for those, though, that would likely rule them out for full page is that they are fairly blurry on the beardies themselves.
Aside from image size as a technical requirement for full page consideration, key photo quality components are a major part of the filtering I do when trying to narrow things down. Sharpness on the beardie is one key thing I do look for (along with general aesthetic, composition, exposure, etc.).
I hope that helped clarify.
