At the suggestion of some of our members, I've changed and added some new default image size options.
First, the default image size for free accounts has now changed from 400px wide to 600px wide. Back when we started, 400px was an ample size for images, due to the use of smaller screens. Now, they just look... small. Additionally, the 400px wide images didn't work very well with our watermark testing. So, we have increased that size.
Pro level members and above now have access to image sizes up to 1000px wide.
I should point out that some of these larger sizes will not work with some of the original site designs. They work perfectly with the new profile format and other website designs that do automatic image sizing. Certain original designs offered at the free level may not appear as intended.
You can access this feature under the "site properties" section.
