how do i change it to jpr or whatever you said and yes its bitmap
Go back to paint and open up the pic that you saved. Then Go to Save as and click On the Arrow for the Dropdown box and click JPEG. Then save it to any folder. Then upload it.
donesnt say that just says loads of colour losses and i clicked the lowest and it went black n white so ill go back and re-do another pic of my best room this time...
