Transferring a pic to photo bucket

[jambo101]

On several forums i participate in there are games that involve posting a picture and members have to name the item in the pic, problem is as most of these pics are derived from Google images the answer is usually given away when clicking on image info as the name of the item is usually right there in the URL or posting the URL of the image info to Google will identify the item under the search function, i was thinking of posting pics to my Photobucket thereby changing the URL and then reposting to the forum game but this doesnt seem to be possible or i dont know how to do it..
As an example posting this pic of a bike and expecting members to guess its name is kinda easy when you right click on the photo and click on Image info and up pops Triumph Trophy tr6



any one have any ideas of disguising a photo's URL from Google images?
Thanks
