I was able to use avatars today, I tried using avatars from my gallery and apparently nothing worked. All the images I have are too large. It turns out that there are special requirements for avatars "120px wide, 80px high, and 100 KiB size". Can this be done automatically? So that images can be automatically resized after uploading?
How many task will do one forum. Now you want this forum to be a image resizer too. Image resizing is very easy, I usually used mobile sample editor tool to resize image.
120x 80x is maximum size forum supported and there is possibility of lower than this. resizing the image will affect the quality so manually doing by self is best and no need of automatic resize however if Theymos want then not a bad idea
