I usually use phototbucket, but what you can do is while on the (polyvore) website, print screen the page --- then open paint, and paste. Then outline the picture, copy it, and then paste it into a new paint page (so there is no background). Then save it. What you can do next is go into the post, and instead click 'go advanced' right next to 'post message.' Then click the 'insert image' button, and it will lead you to go into your computer and click an image (this is how I did it for this contest, instead of going to photobucket - it was quicker for me). And just as an fyi, I like clicking on 'go advanced,' because that way I can preview my post, just to see if it looks the way it's suppossed to. If any of this does't make ANY bit of sense, then just ignore, but I just wanted to try and help you out a little with an alternate way to post pictures on the site. Good luck!
