Your flowing lava is being downloaded correctly. That is the exact image that is on our server. It is not stretching or rescaling it incorrectly upon download at all. I would suggest reuploading it. I assume you uploaded that a long time ago back when the site was a bit buggy.
EDIT: Scratch that. It does something incorrectly upon upload. I'll fix it sometime soon.
If I see any textures that appear to be stolen, I'll make sure to report the packs, and report back here. At the moment, I can only be certain when mine are stolen. There seem to be a lot of copies of Dokucraft-style textures around, but Doku did give freedom of use for his textures, and I'm not sure which are his, and which were made afterwards. Might be worth checking up on a few, though. I'm almost certain some of them are not Doku's free-to-use ones.
Is there any reason that favouriting individual textures doesn't make them get automatically selected when you load the page? If you're using a texture pack that has a lot of textures you have to spend ages selecting the textures you want whenever you update it.
with the supported mods u should make it like u click on the mod and it brings u up to a page that has only that or something like that it's just really hard to find txt packs for mod like industrial craft if u get what i mean
It's quite obviously out of hand now, since you've added several more mods to the support list, but do you guys plan to upload the default images from each of the mods like you did with Minecraft's vanilla textures?
So what are thoughts on possible mods that can be supported? I guess mods YOU use would be the easiest. Maybe perhaps hold polls to see what priorities are when it comes to mod support. I for one would love to see Pchan3's Airship support, but that's just me. (:
We can support any mod. Just spout of suggestions and if you're lucky we'll have time when we read your post and we'll stick it in real quick. Otherwise it gets put on THE LIST.
