 * ```ts
 * const uploaded = await geo.storage.uploadImage({

 *
 * console.log(uploaded.cid);
 * console.log(uploaded.dimensions);

 * @returns The uploaded IPFS URI and detected dimensions when available.
 * @throws When fetch is unavailable, the source URL cannot be fetched, upload fails, or the CID response is invalid.
