then it probaly doesnt do it
it depends on the host settings

but dit you uplaoded that image with that long text ??

that looks to me like a dynamic generated image (i dont think you store images with a lot of numbers and letters :P )

give write permision to that folder and see if it works then
and place a emty index.html file in that folder , so you can get in to that folder with out a error 404 not found :S (fix sometimes a problem to)

and if you got realy bad luck , then it means that that host doesnt support gdlib and doesnt create dynamic images (search for a test file to be sure :D)

if you dont mind spending a bit of money then i can provide hosting and i make it work for you ^^
but i dont do hosting anymore so then you need to contact me :D (this was a bit offtopic)
