I'm trying to crossposts images I post on my blog to my tumblr blog. Everything works fine, except the image is way to small. I upload my images at 650x650px, my featured image is 550x550px but on Tumblr I only get an image with 180x180px. I've tried, IFTTT, Jetpack sharing and Nextscripts. All of them give the same result. Is there a way to force these plugins to use the right image?
I hope someone can help me out with this one.
