Well, the main thing is dealing with the entries that say "this pokemon is on the left in the image" and such. The sizes of the images should be standardized, as should the information... On ones like Poster's that don't have a class or Pokedex entry, it should say something like Class: Input Needed, so that other community members can supply information to complete the entries.
As for the copyright thing, it's not really necessary, but there are people like MetalFlygon08 who make a big show of their tags. I don't know how he would feel about us separating that from his sprites.
If you want to change the Communitydex Photobucket's PW to something unrelated to any accounts you have anywhere else, I can edit the images and upload them... It would be faster than sending them to you. Actually, the ideal would be to make a wiki for the Communitydex; the images could be hosted there, anyone could edit the entries, and the entries in the thread could link to them.
I'd actually made a photobucket account for the communitydex, no lie. I was gonna upload them all but I got bored. I'l do it now if you want. As for the format on the image, I don't think it's necessary if I'm honest. Maybe the letters "PCDex" and just leave it at that.
Hey, I was thinking about standardizing all of the images in the Communitydex and hosting them in one place, to clean things up a bit and make sure that we don't lose anything. Don't worry, if you deem it a good idea I'll insert the new image locations into the workings myself, you'd just have to post it. Anyway, what do you think of this format?
