Is this plugin for me?

You should use WP-Offload if your blog has a considerable amount of traffic and you care about end-user performance. Not only you will gain more performance and responsiveness, but your total bandwidth bill will get smaller.

Do I have to upload my files to the SteadyOffload cache servers?

No. You don't have to upload any files at all. The SteadyOffload cachebot does that - static content gets mirrored and delivered from the SteadyOffload cache servers, but at the same time everything remains stored on your server.

Is my SteadyOffload key private and confidential?

No. Your SteadyOffload key is used primarily for URL differentiation. To prevent bandwidth theft, you can set URL filters through the SteadyOffload control panel.

Is there any limit on the size of the files that can be offloaded?

No. You can offload small text files as well as big downloads like CD images.

How can I refresh an already cached object in case the original has changed?

You should use the custom "xnonce" attribute. Setting a random value to it will tell the SteadyOffload cache servers to synchronize the cached object with the original one immediately.

How can I use WP-Offload to create a thumbnail?

Just use the custom "xmanip" attribute with the "img" and "a" tags. For more details on the available commands within that attribute, please check the SteadyOffload control panel.

Can I compress offloaded images?

Yes. It's possible to set the quality factor of JPEG images through the "xjpegquality" custom attribute.
