I notice a problem with the load time for the insert image function in the blog editor.
This worked great for me to begin with however as I have continued to upload images the load time has slowed such that it is now unusable.
I would guess as this is a single page lookup, then there will be an upper limit reached when the page will timeout.
Can you have a look at paginating (breaking up the photos) or changing so that it loads only the first X (10 ??) photos.
I can get around it by inserting the image url but would be an improvement.
Thanks very much!
