Yes, there are a few restrictions as to the images we can accept:
PERSONAL WATERMARKS AND SIGNATURES:
We watermark your name into all your images, so there's no need to add your own. We have to take down any images that appear with your own watermark or signature.
IMAGES WITH OVERLAID TEXT
Images should be as crisp and clear as possible, images with text overlaid on the image, including date stamps, are not currently accepted
Filtered/edited images are fine, but we do not accept digital artwork, illustrations, paintings or CGI images
There are also a couple of restrictions on the size and file types: images must be a minimum of 800 px across (there are no maximum pixel dimensions), and under 30MB in size.
All images uploaded to Picfair via FTP must also be JPEGs (.jpg or .jpeg). We can’t accept images that are saved as other image types, such as .tif or .png
