clipboardSerializer to convert some nodes to image representations for exporting them to Google Docs etc. (in PM I render them as node views). Basically I have a webservice that can render these nodes to PNG and in clipboardSerializer I generate URLs for this webservice and set them as the img src attributes.
The problem I have is that even though the nodes never get attached to document.body and never rendered in the browser the images are still loaded, which causes unnecessary traffic when you just want to copy or drag-and-drop items around inside PM.
Does anyone have an idea on how to avoid this?
