The sig image! It has the scrollbar of doom!
The only best webspace you can upload anything, with no limitations, and you can leech off until all bandwidth is gone.. is.. your ISP webspace! (If they give you any)
seem good for space, but I think they're like geocities, where you have to rename to .txt
Most sites I've found either need a .txt rename or have bandwidth limitations.
You can try that if you want image hosting.
