mrkgnao: P.S. I'm not a web programmer, so rather new to all of this.
And you're doing a damn fine job hiding it :-)
Spinorial: Also, it would be a convenient option to link to the HTTPS pages on GOG.
mrkgnao: Could you elaborate a bit? What HTTPS pages? What are the benefits and drawbacks of that?
N.B. I'm no web programmer either, so I'm going by cursory knowledge.
HTTPS is a secure protocol which uses SSL to encrypt any data you might send and receive. All game cards and fora have duplicate addresses: the default
http://www.gog.com/<stuff>, and the secure
https://secure.gog.com/<stuff>. Many people prefer to use exclusively the secure ones, whenever available. It's not critical for the purposes of your project, but it's a convenience. GOG itself is at fault here, because a lot of its own links break the secure environment and revert to default http.
Spinorial: Might I suggest you also use the forum icons for the games - this way it also works for the removed ones.
mrkgnao: Not sure I understand. There are already working forum links for the removed one.
So, here's the deal:
Search in MaGOG for all the removed games. You'll notice that there are no icons to display on the left, probably because they're not in the catalogue anymore. However, the fora for these games are still available,
e.g.
https://secure.gog.com/forum/wallace_gromits_grand_adventures Furthermore, if you go to
https://secure.gog.com/forum and search for Wallace, you'll see that the link to the forum has its old icon. These appear to be the same size as the ones you're using, so I suggest you use these to fill the void.
