What you can try is get the original image and run it through
https://www.remove.bg/ . This website cuts out images perfectly i'd say 80% of the time and when it does work it's literally better than photoshop lmao, from there you can lay down a solid colour on ipiccy that you think would compliment the photo the best and then crop, resize, round corners and then save~ If this website doesn't work for you and you can't find any other method then don't worry about it, the badges can still go through voting as is but one of us Awards will have to alter the badge ourselves or we might have to choose the 2nd most voted badge if it's more suitable. We will sort something out!
