Both the pics above are the original size that I uploaded to Smugmug & Flickr
Longest edge is 1600 as that is the maximum size that I can save them from Picasa, my photo editing software. Picasa is the Photoshop for dumb old fuckers like me
When linking them to here I chose "Original" just as a test. Normally I use 1200.
I noticed that your pics were 800 x 600 in your Penarth thread
Can I suggest that you select a larger size and see what happens?
