Of course, we will still be accepting images sized differently, as long as they are below 1600 x 1200px. These won’t display at their best though, which is why we encourage submissions in the new size. A good source of information regarding the club is available on our Information & Knowledge Base Page.
Of course any image that is submitted as a print is not affected by the above. The same conditions apply for prints, as in mounts must be no bigger than 400 x 500mm and no smaller than 250mm x 200mm.
