Dota2 Stats Img - is a simple service that provides your dota2 match making data dynamically in an image, so can be used as a signature. It uses dotabuff statistics, so if there will be nothing - it will show nothing. Note: generated image is cached for 6 hours.
Make sure your dotabuff page is working. If dotabuff page works - contact me.
If you have some suggestion or improvement - contact me.
Account id is your steam 32bit profile which means can be not more than 2^32 = 4294967296. I suppose that's why valve decided to use steam64 bit id's. Less numbers - more elite :D.
Simpliest way is to go to dotabuff and copy your number in dotabuff link
Second way is to use steamidfinder.ru as it supports any input and outputs everything including this steam 32bit profile aka account id.
