why wont my pictures upload into my mp store

[GemstoneHeart]

I have created pictures/files several times using 3 different types of editing programs, created as jpg, jpeg, gif, and png. I've made it in the minimum size for products, exact size for store banner (700x100) and profile picture (45x45). I've made it as plain as plain can be (meaning no extra background or extra effects). I've deleted and started computer fresh from the beginning of creating a file thinking maybe theres a glich on my end just not recognizing anything and I am still getting an error that my attachment content type is not one of the following supported image formats *.jpg, png, gif.  Needless to say I'm beyond frustrated at this point that I can not even get my store up and running on Marketplace. Can someone PLEASSSSSSSSSSSSSE HELP solve this problem???

Hi Gemstone,

Have you tried using a different web browser? Internet Explorer sometimes doesn't play well with SL's web properties.
