How to recreate thumbnail?

Hello,

I would like to thank You for a great service You provide with wImg. It works great and serves its purpose better than expected.

Although wImg is simple to use I have encountered a problem. If someone has already generated a thumbnail for website and after a week the looks of this website were changed the thumbnail would still show the old page. I know that those images are held for few months on the server but is there any way to recreate them manually?

for the moment the webshots are recreated every day, but its only for testing later i will put it back to be recreated every 7 days.

That means if you look at a screenshot that is 8 days old, the system shows you the picture, but also notices it is 8 days old and re-queues the picture in the background. So a few seconds later, if you reload that picture you will see the new updated picture. If you place many pictures on your site and it has sufficient traffic, your pictures will always be pretty much up to date.

Also if the picture happens to be all white (happens sometimes with slow sites) or other *recognized common problem, the picture gets re-queued faster.
