... you are asking your server to load
each external image to find its size
every time the page is called. This
is (ahem) somewhat inefficient.
I would look at your link-adding page:
1. ask users not to link to super-huge
images OR ask for a thumbnail
link as well as the full-size;
2. when links are submitted, get the
image size and store it in a local
database; then get the image size
(and thumbnail-image-size) at
the same time you retrieve the link
(and thumbnail-link)... set the preview
image to the thumbnail, and the anchor
to the full-size image.
