How to link a Flickr image so it shows an image of desired size instead of just a URL:
Go to the image (your second link, for example) on Flickr.
Click the Download arrow at lower right and select "View all sizes"
On the "Photo - all sizes" page, select the size you want.
Right click on the image and select "Copy image address"
Back on videokarma, "go advanced" to show all the options for your post.
Click the "Insert Image" icon (looks like a mountain and sun).
A small window pops up. Press Control-V to copy the URL in the box.
