Green_Hilltop: I totally love your background on your desktop, is that Paphos? Where can I get those, I'd love to use them in my Win 7 background themes. :)
Thanks!
Actually, it's a picture of the island of Santorini. I found it via a Chrome extension which showed landscape pictures upon opening a new tab - I ended up not keeping that extension because I thought the selection of that one wasn't varied (I saw just some more pics of Santorini and some from Tuscany, Italy), so it took me a while to recall its name. It's "Dream Afar New Tab" and you can download any pics you see that you like by going to the bottom left corner of the new tab and clicking the icon with a downwards pointing arrow -this will allow you to save the pic to your pc. I'd attach the picture for you normally, but gog doesn't allow for big images to be attached so... Alternatively, if you don't want to download extensions and/or aren't interested in other pics but only this one, this particular pic can be found elsewhere too:
Here are the google image search results for this pic (shortened by goo.gl)
Green_Hilltop: I see that many of the themes there say they are for Cinnamon, KDE or XFCE, does that mean you have to adjust something to make it work on MATE? Like one of the random themes I clicked on said that if you want to have it work on MATE, you have to adjust xx.
If you mean whether you can use a particular icon theme on several window environments without problems, from my own experience I think you can mostly do so without adjustments. I personally installed the Victory icon theme I saw from Ganni on separate Cinammon, MATE and Xfce virtual machines. It showed up fine on all of these without adjustments, although on Xfce it says that the image cache or something like that is missing but I haven't bothered fixing it, because the theme shows just fine despite that.
