Dear Experts,

Could someone recommend a script or utility one can run from command line
on Linux or UNIX machine to make a snapshot image of webpage?

We have a signage (xibo) and whoever creates/changes content, likes to add
URLs of some webpages there. All works well if these are webpages on our
servers (which are pretty fast), but some external servers often take time
to respond and take time to assemble the page, in addition these servers
sometimes get really busy, and when response is longer than time devoted
for that content in signage window, this window hangs forever with blank
white field until you restart client. Trivial workaround: just to get
snapshot image (as, say daily cron job), and point signage client to that
snapshot definitely will solve it, and simultaneously we will stop bugging
other people servers often without much need for it. I amd trying to avoid
mirroring that URL content, hence I decided not to use wget or curl.

But when I tried to search for some utility or script that makes webpage
snapshot, I discovered that my ability to search degraded somehow...

Thanks for all your pointers!
