So I haven't been here in a while and I noticed that there are a lot of trophies... I mean A LOT!!! What are they for? and how are they used? I see people have ones like "Alien" and "Wii owner" and stuff.
You can buy tags in the DC store for yourself. Click the "visit store" button under your avatar to the left. You can give people trophies by going to their profile (click on their name) and then entering words into the text box and awarding it to them.
If you use GIMP, (Which I incidentally can't stand but put up with anyway) you can add alpha channel, (Layer > Transparency > Add Alpha Channel) then use the fuzzy-select tool to select the areas that should be transparent, and hit the delete key. Then, save the picture in a format that supports transparency, preferably PNG.
Indeed it is, it's an open-source photoshop "replacement." I put it in quotes because I'm not very fond of it. Just google it and download it and have fun experimenting. It's not lame at all, I still use TGF1's graphics editor for most of my art.
