i've only used photobucket and nothing else.. but yeah... the uploader is rly irritating at times when i juz wanna temporarily host a pic in a hurry it'll take like 3-5mins and even worse freezes up Firefox.

Half of the imageshack stuff I see has a preview box that I have to click on which loads another page etc and it's irritating.
Plus yellow frogs are weird.

you can choose to either use the thumbnail or the direct link. they offer thumbnails cause they use less of their bandwidth.

In that case I dislike the Frog.
