Ok I just decided to rearrange my gallery.
No more max 900 px image size, no more watermarks in the middle of the image....... forget about that!
Bigger files, less obtrusive watermarks and a few images will get some changes and adjustments.
I am aware that I will lose all of the favourites and comments on those artworks, but these things really annoy me and just updating the image with a bigger version is not really what I want.
So prepare to be revamped gallery >: D
